Closes#36557
PiperOrigin-RevId: 639073741
Disable the ConfigVar because it wont work anymore.
As on 30 May 2024, about 40% of the instances of gpr_log are migrated to absl LOG.
The remaining instances will be migrated soon.
Given this situation, it would be a little weird to keep this ConfigVar.
Because half the things will log via gpr_log and the others will log through LOG directly.
For the same reason, the platform specific logging code has been deleted. https://github.com/grpc/grpc/pull/36120
This needs to be deleted too.

Add a dynamic registration mechanism for a new kind of context: one that lives in an arena.
An upcoming set of changes will move all of the legacy context types into this mechanism.
It's likely we'll move other promise based context types to this mechanism also, until the only promise-based context type is `Arena`.

Make `Arena` be a refcounted object.
Solves a bunch of issues: our stack right now needs a very complicated dance between transport and surface to destroy a call, but with this scheme we can just hold a ref to what we need in each place and everything works out.
Removes some `ifdef`'d out code that had been sitting dormant for a year or two also -- I'd left it in as a hedge against it being maybe a bad idea, but it looks like it's not needed.

This turned out to be a known issue described at https://github.com/google/sanitizers/issues/1017 and there is much to do other than disabling the ODR test. I gave a try to "-mllvm -asan-use-private-alias=1" option but it didn't change the result so I turned into this way.

Implements https://github.com/grpc/proposal/pull/429
Currently, the behavior of `GRPC_ARG_HTTP2_MAX_PINGS_WITHOUT_DATA` blocks more pings from being sent if we are sending too many pings without a data/header frame being sent as well. The original intention of this channel arg was to play nice with proxies that have restrictive settings when it comes to pings. This causes awkwardness when configuring keepalive pings for transports with long lived streams with sparse communication. In such a case, gRPC Core would stop sending keepalive pings since no data/header frame is being sent, resulting in a situation where we are unable to detect whether the transport is alive or not.
This change adds an experiment "max_pings_wo_data_throttle" to modify the behavior of `GRPC_ARG_HTTP2_MAX_PINGS_WITHOUT_DATA` to throttle pings to a frequency of 1 minute instead of completely blocking pings when too many pings have been sent without data/header frames.

PiperOrigin-RevId: 638003273
This fixes a fairly embarrassing bug and lack of testing from #33234. Prior to this fix, attempting to use the "tls" creds type would always cause a crash.
@gtcooke94@matthewstevenson88 Note that the root cause of this bug was that when I wrote this code, I assumed that `grpc_tls_credentials_options` had a reasonable default for the cert verifier. But it turns out that it doesn't do that directly; instead, we are only imposing that default in [`CredentialOptionSanityCheck()`](621aa4e5ce/src/core/lib/security/credentials/tls/tls_credentials.cc (L85)), which is called only when we call [`grpc_tls_credentials_create()`](621aa4e5ce/src/core/lib/security/credentials/tls/tls_credentials.cc (L160)), not when we directly instantiate `TlsCredentials` as my code was doing. As part of the TlsCreds API cleanup you're working on, we should fix this so that callers get the right behavior even if they are internal callers that instantiate the TlsCreds object directly rather than calling the C-core API.

Introduce "Yodel" - a framework for testing things vaguely related to calls.
This is breaking up some work I did for transport test suites - we've got a nice way of spawning test-only promises and tracking them visually, and support for setting up an environment that can run as a test or a fuzzer. I'm making that piece a little more reusable, and then rebasing the transport test suite atop that infrastructure.

Public Changes -
* Add a pkgconfig installer for `grpcpp_otel_plugin`
Example Changes -
* Add example of how to use the pkgconfig for `grpcpp_otel_plugin` with the existing OpenTelemetry example.
* Add another OpenTelemetry example that uses OTel's OStream exporter. This makes it easier to test the pkgconfig file for `grpcpp_otel_plugin` since the OStream exporter does not require any additional dependencies, as opposed to the Prometheus exporter.
Test changes -
* Modify `run_distrib_test_cmake_pkgconfig.sh` test to install opentelemetry and build the example with the OStream exporter.

[grpc][Gpr_To_Absl_Logging] Migrating from gpr to absl logging - gpr_log
In this CL we are migrating from gRPCs own gpr logging mechanism to absl logging mechanism. The intention is to deprecate gpr_log in the future.
We have the following mapping
1. gpr_log(GPR_INFO,...) -> LOG(INFO)
2. gpr_log(GPR_ERROR,...) -> LOG(ERROR)
3. gpr_log(GPR_DEBUG,...) -> VLOG(2)
Reviewers need to check :
1. If the above mapping is correct.
2. The content of the log is as before.
gpr_log format strings did not use string_view or std::string . absl LOG accepts these. So there will be some elimination of string_view and std::string related conversions. This is expected.

Right now there's no ordering between the set context from the SetCall callback chain in server.cc, and the read context a few lines down from the new if statement inserted here -- that is if a call is cancelled whilst the server is initializing the context we see a tsan race.
Until https://github.com/grpc/grpc/pull/36598 this was a non-issue however because we were entirely discarding the cancellation edge. Now that we've gotten that back again, this race is appearing.
I'd like us to fix this properly, but to do so probably needs some deeper work on what contexts are and how they're initialized -- and that's not for this week (but maybe this month).
