As part of the dualstack backend designs, subchannels will be created
lazily. Therefore, instead of asserting that there is 1 READY subchannel
and `n - 1` IDLE subchannels, we just assert that there is 1 READY
subchannel.

Adds experimental fork support to gRPC/Ruby
Works towards https://github.com/grpc/grpc/issues/8798 (see caveats for why this wasn't marked fixed yet)
Works towards https://github.com/grpc/grpc/issues/33578 (see caveats for why this wasn't marked fixed yet)
This leverages existing `pthread_atfork` based C-core support for
forking that python/php use, but there's a bit extra involved mainly
because gRPC/Ruby has additional background threads.
New tests under `src/ruby/end2end` show example usage.
Based on https://github.com/grpc/grpc/pull/33495
Caveats:
- Bidi streams are not yet supported (bidi streams spawn background
threads which are not yet fork safe)
- Servers not supported
- Only linux supported
tcp_posix_test is incorrectly assuming that all endpoint_writes with
timestamps enabled will be successfully traced. Remove the timestamps
checking related tests to prevent flakes when the test is enabled
internally.
Similar to https://github.com/grpc/grpc/pull/33542.
Note that there's a ticket to automatically use the one specified in the
--server_image_canonical flag, but for now we just hardcode.

Adds a test for the experiments codegen. It updates the codegen to parse
test_experiments.yaml and test_experiments_rollouts.yaml files and
generate test_experiments.h and test_experiments.cc files along with an
experiments_test.cc file. The experiments test verifies the returned
value of IsExperimentEnabled with the expected value.
Add bazel dependency on opentelemetry-cpp.

PanCakes to the rescue!
We noticed that our 'sanity' test was going to fail, but we think we can
fix that automatically, so we put together this PR to do just that!

This adds pre-built library for aarch64 linux, will help improve the
install speed and avoid building environment issues at customer side.
@apolcyn @jtattermusch Can you help build and push the new rake compiler

Will update the tag and hash after the image is available

Noticed some inconsistencies in our keepalive configuration -
* Earlier, even if keepalive pings were disabled, we would be scheduling
keepalive pings at an interval of INT_MAX ms.
* We were not using `g_default_client_keepalive_permit_without_calls` /
`g_default_server_keepalive_permit_without_calls`. They are both false
by default but they can be overridden in
`grpc_chttp2_config_default_keepalive_args`.

This is a no-op, just reordering `requirements.lock`.
By providing `-r requirements.txt` to `pip freeze` it's able to break up
dependencies required via `requirements.txt`, and sub-dependencies
installed to satisfy them.
I've got a hypothesis that we're losing isolation between test shards
right now for "some reason".
This is a change to reflect test sharding in the port distribution that
we use, in an attempt to alleviate that.

The following bugs are fixed:
* Missing ExecCtx in event engine endpoints and listeners
* Ref counting issue with iomgr endpoint which causes crashes in
overloaded situations
The PR includes a test which triggers these bugs by simulating an
overloaded system.
- 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`.
`cmake_ninja_vs2019` and `default` are using the same
`cmake_ninja_vs2019` so having two tests are waste so this is removing
`cmake_ninja_vs2019` leaving `default` which does `cmake_ninja_vs2019`.
This change can cut the space consumption by half and with 250GB disc,
- Pre-test: 267,770,322,944 bytes free
- Post-test: 134,499,295,232 bytes free
Do not clutter the final error we see at the end with the before/after
stats.

The approach of doing a recursive function call to expand the if checks
for known metadata names was tripping up an optimization clang has to
collapse that if/then tree into an optimized tree search over the set of
known strings. By unrolling that loop (with a code generator) we start
to present a pattern that clang *can* recognize, and hopefully get some
more stable and faster code generation as a benefit.

Improvements to the `LoadBalancerAccumulatedStatsRequest` output. Makes
it readable.
This greatly affects `assertRpcStatusCodes()` output, used in authz and
custom_lb.
No before and after stats, just useful diff stats from now. Minimal and
readable.
Also diff stats have `rpcs_started` now.
Output example:
```
--- Starting subTest __main__.AuthzTest.test_plaintext_allow.01_host_wildcard ---
[psm-grpc-client-765bfbf868-jqjm7:51561] >> RPC LoadBalancerStatsService.GetClientAccumulatedStats(request=LoadBalancerAccumulatedStatsRequest({}), wait_for_ready=True, timeout=600)
[psm-grpc-client-765bfbf868-jqjm7:51561] >> RPC XdsUpdateClientConfigureService.Configure(request=ClientConfigureRequest({'types': ['EMPTY_CALL'], 'metadata': [{'key': 'test', 'value': 'host-wildcard'}]}), timeout=5, wait_for_ready=True)
[psm-grpc-client-765bfbf868-jqjm7:51561] >> RPC LoadBalancerStatsService.GetClientAccumulatedStats(request=LoadBalancerAccumulatedStatsRequest({}), wait_for_ready=True, timeout=600)
[psm-grpc-client-765bfbf868-jqjm7:51561] >> RPC LoadBalancerStatsService.GetClientAccumulatedStats(request=LoadBalancerAccumulatedStatsRequest({}), wait_for_ready=True, timeout=600)
[psm-grpc-client-765bfbf868-jqjm7] << Received accumulated stats difference. Expecting RPCs with status (0, OK) for method EMPTY_CALL.
- method: EMPTY_CALL
rpcs_started: 13
result:
(0, OK): 14
--- Finished subTest __main__.AuthzTest.test_plaintext_allow.01_host_wildcard ---
```
In case of test failure, it'll still print all stats at the end,
including before and after:
```
AssertionError: Expected only status (15, DATA_LOSS), but found status (0, OK) for method UNARY_CALL.
Stats before:
- method: UNARY_CALL
rpcs_started: 2153
result:
(14, UNAVAILABLE): 1674
(0, OK): 479
Stats after:
- method: UNARY_CALL
rpcs_started: 2404
result:
(0, OK): 730
(14, UNAVAILABLE): 1674
Diff stats:
- method: UNARY_CALL
rpcs_started: 251
result:
(0, OK): 251
```
And as I was at it, also made `LoadBalancerStatsResponse` nice:
Fixes the issue introduced in https://github.com/grpc/grpc/pull/33104,
where stopping the current run didn't reset `self.time_start_requested`,
`self.time_start_completed`, `self.time_start_stopped`. Because of this,
the subsetting test (the only one [redeploying the client
app](10001d16a9/tools/run_tests/xds_k8s_test_driver/tests/subsetting_test.py (L73C1-L74)))
started failing with:
```py
Traceback (most recent call last):
File "xds_k8s_test_driver/tests/subsetting_test.py", line 76, in test_subsetting_basic
test_client: _XdsTestClient = self.startTestClient(

raise RuntimeError(
RuntimeError: Deployment psm-grpc-client: has already been started at 2023-05-27T13:47:15.262461
```
This PR:
1. Instead of relying on the `time_start_requested`,
`time_start_stopped` to produce GCP links, tracks the history run of
each deployment. This fixes the issue described above, and adds support
for listing all past runs executed by a k8s runner.
2. Minor: remove the unnecessary call to `test_client.cleanup()` when
there's no past deployment runs (e.g. at the first iteration of `for i
in range(_NUM_CLIENTS):`)
- switch to json_object_loader for config parsing
- use `absl::string_view` instead of `const char*` for cert provider
names
- change cert provider registry to use a map instead of a vector
- remove unused mesh_ca cert provider factory
Allow for multiple `--grpc_experiments`, `--grpc_trace` command line
arguments to be added, accumulate them, and provide them to gRPC as one
thing.
