The approach of doing a recursive function call to expand the if checks
for known metadata names was tripping up an optimization clang has to
collapse that if/then tree into an optimized tree search over the set of
known strings. By unrolling that loop (with a code generator) we start
to present a pattern that clang *can* recognize, and hopefully get some
more stable and faster code generation as a benefit.

Improvements to the `LoadBalancerAccumulatedStatsRequest` output. Makes
it readable.
This greatly affects `assertRpcStatusCodes()` output, used in authz and
custom_lb.
No before and after stats, just useful diff stats from now. Minimal and
readable.
Also diff stats have `rpcs_started` now.
Output example:
```
--- Starting subTest __main__.AuthzTest.test_plaintext_allow.01_host_wildcard ---
[psm-grpc-client-765bfbf868-jqjm7:51561] >> RPC LoadBalancerStatsService.GetClientAccumulatedStats(request=LoadBalancerAccumulatedStatsRequest({}), wait_for_ready=True, timeout=600)
[psm-grpc-client-765bfbf868-jqjm7:51561] >> RPC XdsUpdateClientConfigureService.Configure(request=ClientConfigureRequest({'types': ['EMPTY_CALL'], 'metadata': [{'key': 'test', 'value': 'host-wildcard'}]}), timeout=5, wait_for_ready=True)
[psm-grpc-client-765bfbf868-jqjm7:51561] >> RPC LoadBalancerStatsService.GetClientAccumulatedStats(request=LoadBalancerAccumulatedStatsRequest({}), wait_for_ready=True, timeout=600)
[psm-grpc-client-765bfbf868-jqjm7:51561] >> RPC LoadBalancerStatsService.GetClientAccumulatedStats(request=LoadBalancerAccumulatedStatsRequest({}), wait_for_ready=True, timeout=600)
[psm-grpc-client-765bfbf868-jqjm7] << Received accumulated stats difference. Expecting RPCs with status (0, OK) for method EMPTY_CALL.
- method: EMPTY_CALL
rpcs_started: 13
result:
(0, OK): 14
--- Finished subTest __main__.AuthzTest.test_plaintext_allow.01_host_wildcard ---
```
In case of test failure, it'll still print all stats at the end,
including before and after:
```
AssertionError: Expected only status (15, DATA_LOSS), but found status (0, OK) for method UNARY_CALL.
Stats before:
- method: UNARY_CALL
rpcs_started: 2153
result:
(14, UNAVAILABLE): 1674
(0, OK): 479
Stats after:
- method: UNARY_CALL
rpcs_started: 2404
result:
(0, OK): 730
(14, UNAVAILABLE): 1674
Diff stats:
- method: UNARY_CALL
rpcs_started: 251
result:
(0, OK): 251
```
And as I was at it, also made `LoadBalancerStatsResponse` nice:
Fixes the issue introduced in https://github.com/grpc/grpc/pull/33104,
where stopping the current run didn't reset `self.time_start_requested`,
`self.time_start_completed`, `self.time_start_stopped`. Because of this,
the subsetting test (the only one [redeploying the client
app](10001d16a9/tools/run_tests/xds_k8s_test_driver/tests/subsetting_test.py (L73C1-L74)))
started failing with:
```py
Traceback (most recent call last):
File "xds_k8s_test_driver/tests/subsetting_test.py", line 76, in test_subsetting_basic
test_client: _XdsTestClient = self.startTestClient(
File "xds_k8s_test_driver/framework/xds_k8s_testcase.py", line 615, in startTestClient
test_client = self.client_runner.run(server_target=test_server.xds_uri,
File "xds_k8s_test_driver/framework/test_app/runners/k8s/k8s_xds_client_runner.py", line 110, in run
super().run()

raise RuntimeError(
RuntimeError: Deployment psm-grpc-client: has already been started at 2023-05-27T13:47:15.262461
```
This PR:
1. Instead of relying on the `time_start_requested`,
`time_start_stopped` to produce GCP links, tracks the history run of
each deployment. This fixes the issue described above, and adds support
for listing all past runs executed by a k8s runner.
2. Minor: remove the unnecessary call to `test_client.cleanup()` when
there's no past deployment runs (e.g. at the first iteration of `for i
in range(_NUM_CLIENTS):`)
This is another attempt to add support for vsock in grpc since previous
PRs(#24551, #21745) all closed without merging.
The VSOCK address family facilitates communication between
virtual machines and the host they are running on.
This patch will introduce new scheme: [vsock:cid:port] to
support VSOCK address family.
Fixes#32738.

It's completely legitimate to have a zero in a filename/include guard.

- switch to json_object_loader for config parsing
- use `absl::string_view` instead of `const char*` for cert provider
names
- change cert provider registry to use a map instead of a vector
- remove unused mesh_ca cert provider factory
The PR does the following:
* Splits the single experiments.yaml file into two files:
experiments.yaml and rollouts.yaml.
* The experiments.yaml will now only include experiment definitions. The
default values of the experiments must now be specified in rollouts.yaml
* Removes the 'release' default value because it is not used.
* Adds an additional_constraints character string to ExperimentMetadata.
* Introduces a hook in src/core/lib/experiments/config.h to allow
registering arbitrary experiment constraint validation callbacks. These
callbacks would take an ExperimentMetadata object as input and return
the correct value to use for an experiment subject to additional
constraints.
Most of these data structures need to scale a bit like per-cpu, but not
entirely. We can have more than one cpu hit the same instance in most
cases, and probably want to cap out before the hundreds of shards some
platforms have.

arguments to be added, accumulate them, and provide them to gRPC as one
thing.

`tools/run_tests/sanity/check_absl_mutex.sh` was broken, a missing paren
crashed the script if run locally. It's unclear yet how our sanity
checks were not complaining about this, `run_tests.py` does not save the
log.
I've noticed we add the cleanup hook after setting up the
infrastructure. Thus, if infra setup failed, the cleanup won't work.
This fixes it, and adds extra checks to not call
`cls.test_client_runner` if it's not set.
The logger uses `absl::FPrintF` to write to stdout. After reading a
number of sources online, I got the impression that `std::fwrite` which
is used by `absl::FPrintF` is atomic so there is no locking required
here.

Fail test if client or server pods restarted during test.
#### Testing
Tested locally, test will fail with message similar to:
```
----------------------------------------------------------------------
Traceback (most recent call last):
File "/usr/local/google/home/xuanwn/workspace/xds/grpc/tools/run_tests/xds_k8s_test_driver/framework/xds_k8s_testcase.py", line 501, in tearDown
))
AssertionError: 5 != 0 : Server pods unexpectedly restarted {sever_restarts} times during test.
----------------------------------------------------------------------
Ran 1 test in 886.867s
```
Better logging for `assertRpcStatusCodes`.
(got tired of looking up the status names)
#### Unexpected status found
Before:
```
AssertionError: AssertionError: Expected only status 15 but found status 0 for method UNARY_CALL:
stats_per_method {
key: "UNARY_CALL"
value {
result {
key: 0
value: 251
}
}
}
```
After:
```
AssertionError: Expected only status (15, DATA_LOSS), but found status (0, OK) for method UNARY_CALL:
stats_per_method {
key: "UNARY_CALL"
value {
result {
key: 0
value: 251
}
}
}
```
#### No traffic with expected status
Before:
```
AssertionError: 0 not greater than 0
```
After:
```
AssertionError: 0 not greater than 0 : Expected non-zero RPCs with status (15, DATA_LOSS) for method UNARY_CALL, got:
stats_per_method {
key: "UNARY_CALL"
value {
result {
key: 0
value: 251
}
result {
key: 15
value: 0
}
}
}
```
Before this change, `Found subchannel in state READY` and `Channel to
xds:///psm-grpc-server:61404 transitioned to state ` would dump the full
channel/subchannel, in some implementations that expose
ChannelData.trace (f.e. go) would add 300 extra lines of log.
Now we print a brief repr-like chanel/subchannel info:
```
Found subchannel in state READY: <Subchannel subchannel_id=9 target=10.110.1.44:8080 state=READY>
Channel to xds:///psm-grpc-server:61404 transitioned to state READY: <Channel channel_id=2 target=xds:///psm-grpc-server:61404 state=READY>
```
Also while waiting for the channel, we log channel_id now too:
```
Waiting to report a READY channel to xds:///psm-grpc-server:61404
Server channel: <Channel channel_id=2 target=xds:///psm-grpc-server:61404 state=TRANSIENT_FAILURE>
Server channel: <Channel channel_id=2 target=xds:///psm-grpc-server:61404 state=TRANSIENT_FAILURE>
Server channel: <Channel channel_id=2 target=xds:///psm-grpc-server:61404 state=TRANSIENT_FAILURE>
Server channel: <Channel channel_id=2 target=xds:///psm-grpc-server:61404 state=TRANSIENT_FAILURE>
Server channel: <Channel channel_id=2 target=xds:///psm-grpc-server:61404 state=TRANSIENT_FAILURE>
Server channel: <Channel channel_id=2 target=xds:///psm-grpc-server:61404 state=READY>
```

Similar to what we already do in other test suites:
- Try cleaning up resources three times.
- If unsuccessful, don't fail the test and just log the error. The
cleanup script should be the one to deal with this.
