Instead of initializing the vector to N elements whose values are all
null, we should be reserving N elements before populating the vector.
This bug didn't actually break anything, but it did cause us to allocate
twice the amount of space that we should have.
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.
Just seeing data flowing in after a ping is enough to establish liveness
of a connection, and so we can limit keepalive timeouts to that. Ping
timeouts are necessary for protocol correctness, but may be stuck behind
other traffic, so give them a little more of a grace period.

Split nonbazel test into two; one for bazel build which will be labeled
as required and the other for remining nonbazel tests.

We're not running any test at all from `run_test.py` because of the way
we filter test cases:
1d136fd05f/src/python/grpcio_tests/tests/_runner.py (L137)
* `testcase_filter` is read from a json file (like [this
one](https://github.com/grpc/grpc/blob/master/src/python/grpcio_tests/tests/tests.json))
and test name is similar to `unit._metadata_test.MetadataTest`.
* `case.id()` is loaded by `iterate_suite_cases` and will always have a
prefix of `tests`, an example of case id will be:
`tests.unit._metadata_test.MetadataTest`.
Because of the prefix, none of the test case will be matched thus we're
not running any of the tests.
This PR fixes the prefix issue and all the regressions comes from not
running tests using `run_test.py`.
#### Other Changes
* Added couple of `__init__.py` file since it's required to load tests.
* Added `py_status_code` to Aio rpc state.
* `code()` is expecting to return a python gRPC code but current
`status_code` is a Cython code.
* Added `libsqlite3-dev` to our dockers because it's required for
`coverage==7.2.0`.
* Renamed csds and admin test because test case file have to end with
`_test`:
1d136fd05f/src/python/grpcio_tests/tests/_loader.py (L26)
* Removed gevent test from `run_test.py` because Bazel gevent tests
should be good enough for us.

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

The `TickForDuration()` method was using `grpc_core::Timestamp::Now()`
to get the current time, but that was not in sync with the `now_` value
inside the Fuzzing EE itself, with the result that after two subsequent
250ms increments, timers were not being properly fired. I've added a
test that demonstrates this failure without the fix.
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.

Indeed it seems that on Protobuf side, PROTOBUF_VERSION is defined in
port_def.inc which always comes with a matching include of
port_undef.inc which explicitly undef all macros, among them
PROTOBUF_VERSION. GOOGLE_PROTOBUF_VERSION doesn't suffer from this
issue.
This is a followup of #33646.
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.
This is the initial change of chaotic-good client transport read path,
which is a following PR of the client transport write path at #33876.
There's a pending work of handling endpoint failures in the transport.
It will be added after we have the inter-activity pipe with close
function.

- Fixes support for the same address being present more than once in the
address list, which was accidentally broken in #34244.
- Change the call attribute to encode the hash as an integer instead of
a string.
(I had to first solve a problem with "dubious file ownership" error that
was happening inside the grpc_repo_archive action when using the
concurrent wrapper).
Example:
```
tools/docker_runners/examples/concurrent_bazel.sh --bazelrc=tools/remote_build/linux.bazelrc test --genrule_strategy=remote,local --workspace_status_command=tools/bazelify_tests/workspace_status_cmd.sh //tools/bazelify_tests/test:runtests_csharp_linux_dbg
