This PR is required in order to upgrade to the `master` branch version of protobuf. To do this, we upgrade to the latest version of `rules_python` by:
- Adding in explicit dependencies on all PyPi Bazel test dependencies
- Resolving the circular dependency this creates for `xds-protos` by giving it a Bazel build
- Generating the Python code for `xds-protos` as part of `generate-projects.sh` since doing so directly in Bazel would be highly fragily, dependent on many other projects' Bazel builds

A call execution environment for the V3 runtime.
The `CallFilters` class will ultimately be a (private) member of `CallSpine`, and the `StackBuilder` component will be used by a channel when all of the filters it needs are known to allow the call spine to start processing a call.
This is accompanied by a reasonably extensive test suite.

### Changes in this PR
* Refactor and remove some Core/C++ dependencies to simplify Python Observability package build process.
* Refactored code to read config at Python layer.
* Enable observability build from source.
* Add observability to run_test.
* Currently it's only enabled in Linux.
* Add error handler in run_test loaders.
* Current framework will always visit modules in test directory then decide which tests to skip.
* Since we're not building Observability for MacOS and Windows this step will fail with error `No module named 'grpc_observability'`.
* After the change we'll just skip those modules.
* We still have `_sanity_test` to make sure all tests are loaded correctly for each platform.
* Remov OC dependency as we're migrating to OTel.
* Also removed trace from testing.
* Note that trace propagation function was also removed because of this.
### Testing
* Passed existing tests.
* Tested locally, able to build observability from source using `GRPC_PYTHON_BUILD_WITH_CYTHON=1 pip install .`.

This commit upgrades gRPC to protobuf v25.0 and makes some fixes to
account for upb changes. One major change is that upb has been merged
into the protobuf repo, so we can now drop the separate `@upb`
dependency. Another is that `.upb.c` files no longer exist and there are
new `.upb_minitable.h` and `.upb_minitable.c` files. The longer
filenames exceeded a Windows restriction, so to work around that I
renamed the `upb-generated` directory to just `upb-gen`, and likewise
for `upbdefs-generated`.
To mitigate the following windows long path issue found in
https://github.com/grpc/grpc/pull/34513. Using `pyb` instead of
`python_build` saves 9 characters.

This adds the directory reloader implementation of the CrlProvider. This
will periodically reload CRL files in a directory per [gRFC
A69](https://github.com/grpc/proposal/pull/382)
Included in this is the following:
* A public API to create the `DirectoryReloaderCrlProvider`
* A basic directory interface in gprpp and platform specific impls for
getting the list of files in a directory (unfortunately prior C++17,
there is no std::filesystem, so we have to have platform specific impls)
* The implementation of `DirectoryReloaderCrlProvider` takes an
event_engine and a directory interface. This allows us to test using the
fuzzing event engine for time mocking, and to implement a test directory
interface so we avoid having to make temporary directories and files in
the tests. This is notably not in `include`, and the
`CreateDirectoryReloaderCrlProvider` is the only way to construct one
from the public API, so we don't expose the event engine and directory
details to the user.

Reverts grpc/grpc#34667
The change was reverted because it failed to import to g3, after some
changes, now it's safe to reapply those changes.
Tested by importing this PR internally, it passed presubmit:
cl/573836270
Fix: https://github.com/grpc/grpc/issues/34672
With some recent changes in core, now `grpc_ssl_credentials_create` is
guarded by `gpr_once_init`. In our current implementation, The thread
got `gpr_once_init` lock might require GIL lock during the execution of
`grpc_ssl_credentials_create`, which might cause a deadlock if another
thread is holding GIL lock and waiting for `gpr_once_init` lock.
This change adds `with nogil` to calls to native function
`grpc_ssl_credentials_create` to make sure GIL is released before
calling `grpc_ssl_credentials_create`.

The basic APIs for the CRL Reloading features.
This adds external types to represent CRL Providers, CRLs, and
CertificateInfo.
Internally we will use `CrlImpl` - this layer is needed to hide OpenSSL
details from the user.
GRFC - https://github.com/grpc/proposal/pull/382
Things Done
* Add external API for `CrlProvider`, `Crl`, `CertInfo` (`CertInfo` is
used during CRL lookup rather than passing the entire certificate).
* Add code paths in `ssl_transport_security` to utilize CRL providers
* Add `StaticCrlProvider`
* Refactor `crl_ssl_transport_security_test.cc` so it is more extensible
and can be used with providers
Instead of fixing a target size for writes, try to adapt it a little to
observed bandwidth.
The initial algorithm tries to get large writes within 100-1000ms
maximum delay - this range probably wants to be tuned, but let's see.
The hope here is that on slow connections we can not back buffer so much
and so when we need to send a ping-ack it's possible without great
delay.

We're not running any test at all from `run_test.py` because of the way
we filter test cases:
1d136fd05f/src/python/grpcio_tests/tests/_runner.py (L137)
* `testcase_filter` is read from a json file (like [this
one](https://github.com/grpc/grpc/blob/master/src/python/grpcio_tests/tests/tests.json))
and test name is similar to `unit._metadata_test.MetadataTest`.
* `case.id()` is loaded by `iterate_suite_cases` and will always have a
prefix of `tests`, an example of case id will be:
`tests.unit._metadata_test.MetadataTest`.
Because of the prefix, none of the test case will be matched thus we're
not running any of the tests.
This PR fixes the prefix issue and all the regressions comes from not
running tests using `run_test.py`.
#### Other Changes
* Added couple of `__init__.py` file since it's required to load tests.
* Added `py_status_code` to Aio rpc state.
* `code()` is expecting to return a python gRPC code but current
`status_code` is a Cython code.
* Added `libsqlite3-dev` to our dockers because it's required for
`coverage==7.2.0`.
* Renamed csds and admin test because test case file have to end with
`_test`:
1d136fd05f/src/python/grpcio_tests/tests/_loader.py (L26)
* Removed gevent test from `run_test.py` because Bazel gevent tests
should be good enough for us.

Isolate ping callback tracking to its own file.
Also takes the opportunity to simplify keepalive code by applying the

Adds an experiment to allow multiple pings outstanding too (this was
originally an accidental behavior change of the work, but one that I
think may be useful going forward).

More changes as part of the dualstack design:
- Change resolver and LB policy APIs to support multiple addresses per
endpoint. Specifically, replace `ServerAddress` with
`EndpointAddresses`, which encodes more than one address. Per-address
channel args are retained at the same level, so they are now
per-endpoint. For now, `EndpointAddress` provides a single-address ctor
and a single-address accessor for backward compatibility, so
`ServerAdress` is an alias for `EndpointAddresses`; eventually, this
alias and the single-address methods will be removed.
- Add an `EndpointAddressSet` class, which represents an unordered set
of addresses to be used as a map key. This will be used in a number of
LB policies that need to store per-endpoint state.
- Change the LB policy API's `ChannelControlHelper::CreateSubchannel()`
method to take the address and per-endpoint channel args as separate
parameters, so that we don't need to construct a legacy `ServerAddress`
object as we create a new subchannel for each address in the endpoint.
- Change pick_first to flatten the address list.
- Change ring_hash to use `EndpointAddressSet` as the key for its
endpoint map, and to use the first address of the endpoint as the hash
key.
- Change WRR to use `EndpointAddressSet` as the key for its endpoint
weight map.
Note that support for multiple addresses per endpoint is guarded in RR
by the existing `round_robin_delegate_to_pick_fist` experiment and in
WRR by the existing `wrr_delegate_to_pick_first` experiment.
This PR does *not* include support for multiple addresses per endpoint
for the outlier_detection or xds_override_host LB policies; those will
come in subsequent PRs.

In case of abort, currently we don't log anything, this change added an
`AbortError` as the default error for abort, if any other error
happened, we'll log the error so user will be aware of the other error.

This has been stable for a bit, everywhere that the EventEngine is
enabled. Going forward, I think the event_engine_{client|listener}
experiments can probably be used to regulate thread-pool-specific
issues.

Most recent attempt was #34320, reverted in #34335.
The first commit here is a pure revert. The second commit fixes the
outlier_detection unit test to pass both with and without the
experiment.
This is a follow up to https://github.com/grpc/grpc/pull/34103
That pull request explicitly aimed to introduce shared library builds
for Windows (DLLs) while effecting zero material change to the existing
build pipelines. That aspiration meant that the grpc++_unsecure library
had to be effectively excluded from the build (because including it
would have also included a dependency on openssl, which makes no sense
given its purpose)
This PR addresses that by:
* Extracting the single function in grpc_tls_certificate_provider with a
dependency on openssl into a separate compilation unit
* Including that new .cc file into the grpc library
* Including grpc_tls_certificate_provider and one other source file into
grpc_unsecure for the Windows DLL build only.
* Reinstating the grpc++_unsecure library which is a prerequisite for
many tests.
* Regenerating all files affected by the changes in Bazel BUILD that
introduce the new source file.
This change does affect the operation of other build pipelines - I have
confirmed that it does not break the Linux Bazel build.

### Background
* `distutils` is deprecated with removal planned for Python 3.12
([pep-0632](https://peps.python.org/pep-0632/)), thus we're trying to
replace all distutils usage with setuptools.
* Please note that user still have access to `distutils` if setuptools
is installed and `SETUPTOOLS_USE_DISTUTILS` is set to `local` (The
default in setuptools, more details can be found [in this
discussion](https://github.com/pypa/setuptools/issues/2806#issuecomment-1193336591)).
### How we decide the replacement
* We're following setuptools [Porting from Distutils
guide](https://setuptools.pypa.io/en/latest/deprecated/distutils-legacy.html#porting-from-distutils)
when deciding the replacement.
#### Replacement not mentioned in the guide
* Replaced `distutils.utils.get_platform()` with
`sysconfig.get_platform()`.
* Based on the [answer
here](https://stackoverflow.com/questions/71664875/what-is-the-replacement-for-distutils-util-get-platform),
and also checked the document that `sysconfig.get_platform()` is good
enough for our use cases.
* Replaced `DistutilsOptionError` with `OptionError`.
* `setuptools.error` is exporting it as `OptionError` [in the
code](https://github.com/pypa/setuptools/blob/v59.6.0/setuptools/errors.py).
* Upgrade `setuptools` in `test_packages.sh` and changed the version
ping to `59.6.0` in `build_artifact_python.bat`.
* `distutils.errors.*` is not fully re-exported until `59.0.0` (See
[this issue](https://github.com/pypa/setuptools/issues/2698) for more
details).
### Changes not included in this PR
* We're patching some compiler related functions provided by distutils
in our code
([example](ee4efc31c1/src/python/grpcio/_spawn_patch.py (L30))),
but since `setuptools` doesn't have similar interface (See [this issue
for more details](https://github.com/pypa/setuptools/issues/2806)), we
don't have a clear path to replace them yet.

I have actually only tested this in a form backported to grpc 1.48.4,
and I am not able to test the change to `bazel/_gevent_test_main.py`
directly. However, the backported form allows me to build grpc 1.48.4
for Fedora Rawhide with Python 3.12, and I believe the version in this
PR to be correct—especially, if CI passes for Python 3.11, I believe
this part of the test code will continue to work in Python 3.12.
We added this as an exploratory measure for a customer that thought they
were using open census (this turned out to be emphatically false).
Remove it since it's probably not how we ultimately want to do this, and
wait for something better to come along.

Proposed alternative to https://github.com/grpc/grpc/pull/34024.
This version has a simpler, faster busy-count implementation based on a
sharded set of atomic counts: fast increment/decrement operations,
relatively slower summation of total counts (which need to happen much
less frequently).
- Extract build metadata for some external dependencies from bazel
build. This is achieved by letting extract_metadata_from_bazel_xml.py
analyze some external libraries and sources. The logic is basically the
same as for internal libraries, I only needed to teach
extract_metadata_from_bazel_xml.py which external libraries it is
allowed to analyze.
* currently, the list of source files is automatically determined for
`z`, `upb`, `re2` and `gtest` dependencies (at least for the case where
we're building in "embedded" mode - e.g. mostly native extensions for
python, php, ruby etc. - cmake has the ability to replace some of these
dependencies by actual cmake dependency.)
- Eliminate the need for manually written gen_build_yaml.py for some
dependencies.
- Make the info on target dependencies in build_autogenerated.yaml more
accurate and complete. Until now, there were some depdendencies that
were allowed to show up in build_autogenerated.yaml and some that were
being skipped. This made generating the CMakeLists.txt and Makefile
quite confusing (since some dependencies are being explicitly mentioned
and some had to be assumed by the build system).
- Overhaul the Makefile
* the Makefile is currently only used internally (e.g. for ruby and PHP
builds)
* until now, the makefile wasn't really using the info about which
targets depend on what libraries, but it was effectively hardcoding the
depedendency data (by magically "knowing" what is the list of all the
stuff that e.g. "grpc" depends on).
* After the overhaul, the Makefile.template now actually looks at the
library dependencies and uses them when generating the makefile. This
gives a more correct and easier to maintain makefile.
* since csharp is no longer on the master branch, remove all mentions of
"csharp" targets in the Makefile.
Other notable changes:
- make extract_metadata_from_bazel_xml.py capable of resolving workspace
bind() rules (so that it knows the real name of the target that is
referred to as e.g. `//external:xyz`)
TODO:
- [DONE] ~~pkgconfig C++ distribtest~~
- [DONE} ~~update third_party/README to reflect changes in how some deps
get updated now.~~
Planned followups:
- cleanup naming of some targets in build metadata and buildsystem
templates: libssl vs boringssl, ares vs cares etc.
- further cleanup of Makefile
- further cleanup of CMakeLists.txt
- remote the need from manually hardcoding extra metadata for targets in
build_autogenerated.yaml. Either add logic that determines the
properties of targets automatically, or use metadata from bazel BUILD.

Implement DNS using dns service for iOS.
Current limitation:
1. Using a custom name server is not supported.
2. Only supports `LookupHostname`. `LookupSRV` and `LookupTXT` are not
implemented.
3. Not tested with single stack (ipv4 or ipv6) environment
4. ~Not tested with multiple ip records per stack~ manually tested with
wsj.com
5. Not tested with multiple interface environment
Refactored OpenCensus context propagation flow, now propagation happens
for each call and context will be automatically propagated from gRPC
server to gRPC client.
We're using `execution_context` in OpenCensus since the context is
related to OpenCensus and it helps wrap `contextVar` for us.
### Testing
* Added a new Bazel test case for context propagation.

Fix: #33643.
This change adds `__reduce__` to `AioRpcError` to allow pickle.
### Testing
Added bazel unit test, without this change, test will fail with error:
```
TypeError: AioRpcError.__init__() missing 3 required positional arguments: 'code', 'initial_metadata', and 'trailing_metadata'
```
Why: Cleanup for chttp2_transport ahead of promise conversion - lots of
logic has become interleaved throughout chttp2, so some effort to
isolate logic out is warranted ahead of that conversion.
What: Split configuration and policy tracking for each of ping rate
throttling and abuse detection into their own modules. Add tests for
them.
Incidentally: Split channel args into their own header so that we can
split the policy stuff into separate build targets.

This PR:
- Fixes the xds-protos Python package, which was broken when the `udpa`
submodule was removed
- This required re-adding the protoc-gen-validate submodule
- Adds non-Bazel tests for xds-protos and all of its dependent packages
- Versions xds-protos the same way as the rest of the Python packages
- Fixes Python 3.11 support in `run_tests.py`, which is necessary for
the testing mentioned above
CC @sergiitk You won't be able to consume this in the interop tests
until it makes it into a release. I'm thinking I'll want to backport

CC @drfloob to inform him about the likely backport.
This PR implements a c-ares based DNS resolver for EventEngine with the
reference from the original
[grpc_ares_wrapper.h](../blob/master/src/core/ext/filters/client_channel/resolver/dns/c_ares/grpc_ares_wrapper.h).
The PosixEventEngine DNSResolver is implemented on top of that. Tests
which use the client channel resolver API
([resolver.h](../blob/master/src/core/lib/resolver/resolver.h#L54)) are
ported, namely the
[resolver_component_test.cc](../blob/master/test/cpp/naming/resolver_component_test.cc)
and the
[cancel_ares_query_test.cc](../blob/master/test/cpp/naming/cancel_ares_query_test.cc).
The WindowsEventEngine DNSResolver will use the same EventEngine's
grpc_ares_wrapper and will be worked on next.
The
[resolve_address_test.cc](https://github.com/grpc/grpc/blob/master/test/core/iomgr/resolve_address_test.cc)
which uses the iomgr
[DNSResolver](../blob/master/src/core/lib/iomgr/resolve_address.h#L44)
API has been ported to EventEngine's dns_test.cc. That leaves only 2
tests which use iomgr's API, notably the
[dns_resolver_cooldown_test.cc](../blob/master/test/core/client_channel/resolvers/dns_resolver_cooldown_test.cc)
and the
[goaway_server_test.cc](../blob/master/test/core/end2end/goaway_server_test.cc)
which probably need to be restructured to use EventEngine DNSResolver
(for one thing they override the original grpc_ares_wrapper's free
functions). I will try to tackle these in the next step.

In preparation for implementing the promise based version, separate out
the legacy call data from the filter.
There are two commits here, each representing one phase of this code
movement:
66676d398c moves `class RetryFilter` into
the header and the vtable name into that class, as this will be shared
code between the implementations
4c84f115ad then moves `class
RetryFilter::CallData` into `class RetryFilterLegacyCallData`, and moves
*that* into its own file
Doing so makes me less confused as to what I'm editing going forward.
No functionality should be affected.

More work on the dualstack backend design:
- Change round_robin to delegate to pick_first instead of creating
subchannels directly.
- Change pick_first such that when it is the child of a petiole policy,
it will unconditionally start a health watch.
- Change the client-side health checking code such that if client-side
health checking is not enabled, it will return the subchannel's raw
connectivity state.
- As part of this, we introduce a new endpoint_list library to be used
by petiole policies, which is intended to replace the existing
subchannel_list library. The only policy that will still directly
interact with subchannels is pick_first, so the relevant parts of the
subchannel_list functionality have been copied directly into that
policy. The subchannel_list library will be removed after all petiole
policies are updated to delegate to pick_first.
The address attribute interface was intended to provide a mechanism to
pass attributes separately from channel args, for values that do not
affect subchannel behavior and therefore do not need to be present in
the subchannel key, which does include channel args. However, the
mechanism as currently designed is fairly clunky and is probably not the
direction we will want to go in the long term.
Eventually, we will want some mechanism for registering channel args,
which would provide a cleaner way to indicate that a given channel arg
should not be used in the subchannel key, so that we don't need a
completely different mechanism. For now, this PR is just doing an
interim step, which is to establish a special channel arg key prefix to
indicate that an arg is not needed in the subchannel key.
With some delay, this is a PR for
https://github.com/grpc/grpc/issues/32564 (and previously
https://github.com/grpc/grpc/pull/31791).
I looked into adding a regular `py_test` for this change [as
suggested](https://github.com/grpc/grpc/pull/31791#issuecomment-1423245116)
but I am not aware of any effect that the presence of a .pyi stub file
would have at runtime and where some sort of type-checking in a .py
script would be affected. Stub files are only for use by type checkers &
IDE's. I mean, something like this would work:
```
import helloworld_pb2
py_file = helloworld_pb2.__file__
pyi_file = py_file + 'i’
self.assertTrue(os.path.exists(pyi_file))
```
But that seems really hacky to me. Instead I created a simple rule test
for `py_proto_library` with Bazel Skylib which tests the declared
outputs for an example `py_proto_library` target. Indirectly, this also
tests that the declared output files are actually generated. Please let
me know if this is sufficient.
- Switched from yapf to black
- Reconfigure isort for black
- Resolve black/pylint idiosyncrasies
Note: I used `--experimental-string-processing` because black was
producing "implicit string concatenation", similar to what described
here: https://github.com/psf/black/issues/1837. While currently this
feature is experimental, it will be enabled by default:
https://github.com/psf/black/issues/2188. After running black with the
new string processing so that the generated code merges these `"hello" "
world"` strings concatenations, then I removed
`--experimental-string-processing` for stability, and regenerated the
code again.
To the reviewer: don't even try to open "Files Changed" tab 😄 It's
better to review commit-by-commit, and ignore `run black and isort`.

This is a hack to get around an issue on Apple devices caused by the
PosixEventEngine's `poll` poller not supporting fork. This PR disables
the EventEngine poller entirely in Python builds. It will therefore
prevent the release of the EventEngine generally, and prevent any
testing of EventEngine integration with gRPC Python, until the `poll`
poller is fixed.
This is another attempt to add support for vsock in grpc since previous
PRs(#24551, #21745) all closed without merging.
The VSOCK address family facilitates communication between
virtual machines and the host they are running on.
This patch will introduce new scheme: [vsock:cid:port] to
support VSOCK address family.

Most of these data structures need to scale a bit like per-cpu, but not
entirely. We can have more than one cpu hit the same instance in most
cases, and probably want to cap out before the hundreds of shards some
platforms have.

Reverts grpc/grpc#33088
The internal test is failing because after the change, transitive
dependencies will be included in response too, thus we need add
`empty2_pb2` to response since it's a dependency of
`empty2_extensions_pb2`.
We already did that in OSS test, we need do the same for internal test
case.
The logger uses `absl::FPrintF` to write to stdout. After reading a
number of sources online, I got the impression that `std::fwrite` which
is used by `absl::FPrintF` is atomic so there is no locking required
here.

With these, it is actually possible to have typed client stubs where the
return type is correctly inferred.
It's only for the non-streaming calls, because there is
`RequestIterableType` for the streaming ones (but it's just Any with
extra steps and would require much more work).

Reverts grpc/grpc#32924. This breaks the build again, unfortunately.

```
error: module .../grpc/test/core/event_engine/cf:cf_engine_test does not depend on a module exporting 'grpc/support/port_platform.h'

@sampajano I recommend looking into CI tests to catch iOS problems
before merging. We can enable EventEngine experiments in the CI
generally once this PR lands, but this broken test is not one of those
experiments. A normal build should have caught this.

From comments in https://github.com/grpc/grpc/issues/18075, `CPython`
reinitialize the `GIL` after `pthread_atfork` child handler, thus we
shouldn't use any `GIL` related functions in child handler which is what
we're currently doing, this PR uses `os.register_at_fork` to replace
`pthread_atfork` to prevent any undesired bevahior.
This also seems to fixes a thread hanging issue cased by changes in
core: https://github.com/grpc/grpc/pull/32869
### Testing:
* Passed existing fork tests. (Note that due to some issues in `Bazel`,
this change was not verified by `Bazel runs_per_test`).
* Tested by patch the core PR, was able to fix Python fork tests:
