The current fixed minimum starting thread count (2 threads), combined
with the fixed thread spawn rate limit of 1/sec, was causing test issues
with some new EventEngine integrations.
For example, this test had a race wherein the alarm destructor was
expected to run within 1 second. In 5% of runs, the 2 EventEngine
threads were otherwise occupied, and it would take around 1 second to
spawn a new thread.

Modeled after mutexes in the Rust ecosystem: the mutex owns the data
provided, and acquisition of the mutex returns a handle with which to
manipulate that data.
This fits in nicely with the execution environment we've established
whereby we may want to pass the lock from lambda to lambda for some
time.

Add a config to experiments & rollouts to allow dependent experiments to
be flagged.
We're getting past the point where it's possible to reason about which
experiments need to be turned off if we disable some other experiment,
and so this provides some additional rollout safety.
Can be specified in both experiments and rollouts: experiments.yaml
makes the most sense and we should default to it, but rollouts.yaml lets
us put dependencies between internal & external dependencies internally
and that's gonna be a little useful.

This is a follow-up PR of #34191, which handles the error condition of
endpoints failed to write/read in chaotic-good client transport.
This PR needs to be merged after #34191.

- Fix deadlock in load reporting tests.
- Add timeout to `WaitForLoadReport()`. (Note: this required changing
from `grpc::internal::Mutex` and friends to `grpc_core::Mutex` and
friends.)
- Fix balancer stream shutdown machinery.
- Change `ServerThread` to be a class instead of a struct.
datetime.utcnow() raises a deprecation warning on Python 3.12, so this
change prevents that deprecation warning while also switching to a
monotonic clock for calculating RPC latency

Now we log pretty much identical message:
```

This PR will log the latest channel state in the first message, similar
to what we do in `find_server_channel_with_state`:
52c08f4498/tools/run_tests/xds_k8s_test_driver/framework/test_app/client_app.py (L367-L371)
After the change:

Changes to fake resolver:
- Add `WaitForReresolutionRequest()` method to fake resolver response
generator to allow tests to tell when re-resolution has been requested.
- Change fake resolver response generator API to have only one mechanism
for injecting results, regardless of whether the result is an error or
whether it's triggered by a re-resolution.
Changes to grpclb_end2end_test:
- Change balancer interface such that instead of setting a list of
responses with fixed delays, the test can control exactly when each
response is set.
- Change balancer impl to always send the initial LB response, as
expected by the grpclb protocol.
- Change balancer impl to always read load reports, even if load
reporting is not expected to be enabled. (The latter case will still
cause the test to fail.) Reads are done in a different thread than
writes.
- Allow each test to directly control how many backends and balancers
are started and the client load reporting interval, so that (a) we don't
waste resources starting servers we don't need and (b) there is no need
to arbitrarily split tests across different test classes.
- Add timeouts to `WaitForAllBackends()` functionality, so that tests
will fail with a useful error rather than timing out.
- Improved ergonomics of various helper functions in the test framework.
In the process of making these changes, I found a couple of bugs:
- A bug in pick_first, which I fixed in #34885.
- A bug in grpclb, in which we were using the wrong condition to decide
whether to propagate a re-resolution request from the child policy,
which I've fixed in this PR. (This bug probably originated way back in
#18344.)
This should address a lot of the flakes seen in grpclb_e2e_test
recently.
Roll forward #34657, which was reverted in #34761.

This fixes a bug accidentally introduced in #33753. The symptom is that
if we exit idle and then get a new address list before any of the
subchannels in the old list can report their initial connectivity state,
we will incorrectly ignore the new address list.
EventEngine experiments, especially with `work_serializer_dispatch` tend
to cause callbacks to occur later than we've previously seen, so tests
that verify global data structures tend to become flakier when these are
introduced.
Here, the fix is waiting for EventEngine to be closed before starting
the new test.
Whilst here, make some adjustments to the test for better readability on
what's going on:
- if we fail a request to an echo service, we do not actually expect the
messages to match, so don't report that
- if we expect a value of 1 or 2, AnyOf is a better tool: it will report
the actual value too

Eliminate spam from clang-format script.
Also add a shuffle to the file list - saves about a second of runtime on
my machine by making sure clusters of hard files are distributed evenly
amongst CPUs.
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.

This PR fixes a bug identified in #29667, where the TLS channel
credentials still require a trust bundle even if the user has explicitly
opted to not verify the server certificate. This PR is based on #29810.
Address https://github.com/grpc/grpc/issues/12554
The API for `duplicate_without_call_credentials` says
```
// Creates a version of the channel credentials without any attached call
// credentials. This can be used in order to open a channel to a non-trusted
// gRPC load balancer.
```
As the impl stands right now, because of that description, in the case
of layered composite creds, I think the right behavior would be to call
down until you get the base cred with no call cred.
In discussing with the team, we do wonder if the use-case of layered
composite creds is really something that should be a feature, or if we
should be checking during the creation of composite creds to make sure
we aren't layering composite creds? @markdroth can you give your
thoughts?
This only affects pull requests for the `Bazel RBE Build Tests` job. The
equivalent master CI job will still build all end2end tests, including
experiments.
Built upon @Vignesh2208 's work in #33156
This adds ref counting to the http_proxy fixture object, fixing test
flakes identified by the introduction of EventEngine listeners. Proxy
objects were either being deleted twice, or sometimes not at all,
resulting in two different sorts of flakes.
The `bazel_build_with_strict_warnings_linux` job was taking nearly an
hour to complete. This change brings it down to ~20m by splitting up the
build targets into 7 separate RBE actions.

This reduces clang-format duration to under 10s on my 128 core machine.
Previously I stopped the process at 10 minutes. Major changes:
Eliminates 18,000 files
```
find ... \
-and -not -path '*/cmake/build/*' \
-and -not -path '*/huffman_geometries/*' \
```
Also, this now runs `$CPU_COUNT` number of parallel clang-format
processes with a roughly equal number of files. Previously, this script
was formatting one file at a time in separate processes (`xargs -n 1`).
Not all POSIX platforms have rt as a separate library. QNX has rt as
part of libc (same as pthreads).
Add condition to check if the library can be found and link with it only
in positive scenario.
