There is a continuous failure in the master/windows/bazel_rbe/grpc_bazel_rbe_opt tests. These generate a lot of noise at the moment, and may be hiding other issues, so they are being disabled in CI.

Disabling before the 1.62 branch cut.
There is a flake in one specific interop test: cloud_to_prod_auth:c++:*:oauth2_auth_token:tls, with * being default or gateway_v4. There is also an unresolved PHP crash on test shutdown, just debug builds on Mac (not Linux or Windows).

The client promise code seems to cause a problem with iomgr pollset shutdown which is causing flakiness.
Right now I don't think it's likely that we'll get this code rolled out before the event engine client lands, so I'm making the experiment dependent on event engine polling.

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.

Cancel streams if we have too much concurrency on a single channel to
allow that server to recover.
There seems to be a convergence in the HTTP2 community about this being
a reasonable thing to do, so I'd like to try it in some real scenarios.
If this pans out well then I'll likely drop the
`red_max_concurrent_streams` and the `rstpit` experiments in preference
to this.
I'm also considering tying in resource quota so that under high memory
pressure we just default to this path.

Noticed that our behavior conflicts with what's mandated:
https://www.rfc-editor.org/rfc/rfc9113.html#section-5.1.2
So here's a quick fix - I like it because it's not a disconnection,
which always feels like one outage avoided.

Instead of fixing a target size for writes, try to adapt it a little to
observed bandwidth.
The initial algorithm tries to get large writes within 100-1000ms
maximum delay - this range probably wants to be tuned, but let's see.
The hope here is that on slow connections we can not back buffer so much
and so when we need to send a ping-ack it's possible without great
delay.
Experiment 1: On RST_STREAM: reduce MAX_CONCURRENT_STREAMS for one round
trip.
Experiment 2: If a settings frame is outstanding with a lower
MAX_CONCURRENT_STREAMS than is configured, and we receive a new incoming
stream that would exceed the new cap, randomly reject it.

Cap requests per read, rst_stream handled per read.
If these caps are exceeded, offload processing of the connection to a
backing thread pool, and allow other connections to make progress.
Previously chttp2 would allow infinite requests prior to a settings ack
- as the agreed upon limit for requests in that state is infinite.
Instead, after MAX_CONCURRENT_STREAMS requests have been attempted,
start blanket cancelling requests until the settings ack is received.
This can be done efficiently without allocating request state
structures.
