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.

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.

In real services most of our time ends up in the `Read1()` function,
which populates one byte into the bit buffer.
Change this to read in as many as possible bytes at a time into that
buffer.
Additionally, generate all possible (to some depth) parser geometries,
and add a benchmark for them. Run that benchmark and select the best
geometry for decoding base64 strings (since this is the main use-case).
(gives about a 30% speed boost parsing base64 then huffman encoded
random binary strings)

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.

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!

It introduces the following syntax:
The following would mark the experiment as broken on ios, false on
windows and debug on posix. If a platform is un-specified, the default
for that platform will be set to false. Refer to
test/core/experiments/fixtures/test_experiments_rollout.yaml for
examples which are tested.
- name: experiment_1
default:
ios: broken
windows: false
posix: debug
It also supports the already existing syntax and interprets it as just
specifying one default for all platforms.
Supported platform tags: ios, windows, posix
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.

This adds a new channel argument `GRPC_ARG_DSCP` which allows users to
create classified gRPC streams with a
Differentiated Services Code Point (DSCP) marking on the IP frames.
The channel argument is handled on both clients and servers, but
currently only on posix based systems.
Fixes#17225
**Background**:
In addition to what is already described is #17225, when gRPC is used in
telco systems there is often a need to classify streams of importance.
There can be multiple hops between two endpoints (e.g. between 2 telecom
operators) and some streams that are more important than others (e.g.
emergency call related or similar). By marking the IP packets using DSCP
the aware routers can make a sound decision of the prioritization.
This PR propose to use DSCP as the configuration value since its common
for both IPv4/IPv6, an alternative would be to use a config name that
includes TOS and Traffic Class.
There might be more needed regarding documentation and end2end testing,
but there I need some advice.

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.
This PR does the following: for the TLS server credentials, stops
calling `SSL_CTX_set_client_CA_list` by default in
`ssl_transport_security.cc`, and gives users a knob to re-enable calling
this API.
## What does the `SSL_CTX_set_client_CA_list` API do?
When this API is called, a gRPC TLS server sends the following data in
the ServerHello: for each certificate in the server's trust bundle, the
CA name in the certificate.
This API does not change the set of certificates trusted by the server
in any way. Rather, it is just providing a hint to the client about what
client certificate should be sent to the server.
## Why are we removing the use of `SSL_CTX_set_client_CA_list` by
default for the TLS server credentials?
Removing the use of this API by default has 2 benefits:
1. Calling this API makes gRPC TLS unusable for servers with a
sufficiently large trust bundle. Indeed, if the server trust bundle is
too large, then the server will always fail to build the ServerHello.
2. Calling this API is introducing a huge amount of overhead (1000s of
bytes) to each ServerHello, so removing this feature will improve
connection establishment latency for all users of the TLS server
credentials.
More work on the dualstack backend design:
- Change ring_hash policy to delegate to pick_first instead of creating
subchannels directly.
- Note that, as mentioned in the WIP gRFC, because we lazily create the
pick_first child policies, so there's no need to swap over to a new list
as an atomic whole. As a result, we don't use the endpoint_list library
in this policy; instead, we just update a map in-place.
- Remove now-unused subchannel_list library.
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.
Add bazel dependency on opentelemetry-cpp.

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.

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`.
