All TraceFlags are now configured in `src/core/lib/debug/trace_flags.yaml`. The format is:
```
my_flag:
default: false # the default value; default=false
description: Some Description
debug_only: false # debug_only flags only work in debug builds; default=false
internal: false # internal flags will not show up in documentation; default=false
```
To regenerate the trace flag source code, run `tools/codegen/core/gen_trace_flags.py` (requires mako). This script is also run when sanity checking.
This PR also adds two new features:
### Glob-based flag configuration
Trace flag configuration now supports `?` (single wildcard character) and `*` (one or more wildcard characters). For example, using `GRPC_TRACE='event_engine*'` will enable all flags that match that glob. It expands to:
* event_engine
* event_engine_client_channel_resolver
* event_engine_dns
* event_engine_endpoint
* event_engine_endpoint_data
* event_engine_poller
### A cleaner trace-logging macro in abseil logging format
If your goal is only to add log statements when the `fault_injection_filter` trace flag is enabled, you can use the macro:
```
GRPC_TRACE_LOG(fault_injection, INFO) << "Filtered:" << 42;
```
When the trace flag is enabled, the the log will show something like this:
```
I0000 00:00:1715733657.430042 16 file.cc:174] Filtered:42
```
----
Note: just like with the gpr_log to abseil logging conversion, the pre-existing trace logging usages can be replaced with the new tracing macro across multiple PRs.

Noticed this feature was missing from the list, so I added it.
@murgatroid99 - is this supported in Node? Let me know what version and I'll include it.

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.

I was surprised to see that the C++ core interprets "grpc-accept-encoding: deflate" like HTTP: it compresses messages using zlib with deflate compression, rather than using raw deflate. Matching HTTP semantics makes sense, of course, but this misnomer has historically confused HTTP implementations too.
This detail didn't seem important enough to warrant inclusion in the main protocol specification, so I've proposed an addition to `docs/compression.md` to document the expected behavior. I'm happy to move the addition around if you'd prefer it elsewhere.

Tested locally by running `python setup.py doc`, no more errors from observability.
Only error is related to grpc_status:
```

`succeed-on-retry-attempt-<int>` is what is being currently used in the
Java server implementation and also by the test client. The spec was
probably written after the stuff was implemented and this typo is better
fixed before other languages implement their server side logic. Go is in
the process of doing so.
- add entry for aggregate and logical DNS cluster support
- add entry for least_request LB policy
- add a bunch of missing versions in various languages
Fix b/304114403
- adds a new experimental tracer useful for diagnosing ping timeout
failures in unit tests
- adds a pair of experimental tracers for fuzzing event engine
- fix the behavior of FuzzingEventEngine so that a RunAfter(0, ...) runs
in the same tick
- up the rate of sends (reduce the send delay) so we guarantee to be
able to send 200kb/sec in fuzzed e2e unit tests

- Upgrade bazel
- Reduce the number of places where bazel version needs to be upgraded
in future.
- also make sure the list of bazel versions to test by bazelified tests
is loaded from supported_versions.txt (it was hardcoded before).
- ~~Try upgrading windows RBE build to bazel 6.3.2 as well.~~
The core idea:
- the source of truth for supported bazel versions is in
`bazel/supported_versions.txt`
- the first version listed in `bazel/supported_versions.txt` is
considered to be the "primary" bazel version and is going to be used in
most places thoroughout the repo.
- use templates to include the primary bazel version in testing
dockerfiles and in a newly introduced `.bazelversion` files (which gets
loaded by our existing `tools/bazel` wrapper).
~~Supersedes https://github.com/grpc/grpc/pull/33880~~
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.
