`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.

We shouldn't depend on how much the compression algorithm compresses the
bytes to. This is causing flakiness internally.

This PR aims to de-experimentalize the APIs for GCP Observability.
We would have ideally wanted public feedback before declaring the APIs
stable, but we need stable APIs for GA.
Changes made after API review with @markdroth @veblush, @ctiller and the
entire Core/C++ team -
* The old experimental APIs `grpc::experimental::GcpObservabilityInit`
and `grpc::experimental::GcpObservabilityClose` are now deprecated and
will be deleted after v.1.55 release.
* The new API gets rid of the Close method and follows the RAII idiom
with a single `grpc::GcpObservability::Init()` call that returns an
`GcpObservability` object, the lifetime of which controls when
observability data is flushed.
* The `GcpObservability` class could in the future add more methods. For
example, a debug method that shows the current configuration.
* Document that GcpObservability initialization and flushing (on
`GcpObservability` destruction) are blocking calls.
* Document that gRPC is still usable if GcpObservability initialization
failed. (Added a test to prove the same).
* Since we don't have a good way to flush stats and tracing with
OpenCensus, the examples required users to sleep for 25 seconds. This
sleep is now part of `GcpObservability` destruction.
Additional Implementation details -
* `GcpObservability::Init` is now marked with `GRPC_MUST_USE_RESULT` to
make sure that the results are used. We ideally want users to store it,
but this is better than nothing.
* Added a note on GCP Observability lifetime guarantees.

Earlier, we were simply using a 64 bit random number, but the spec
actually calls for UUIDv4.

This PR adds the view `grpc.io/client/api_latency` for GCP Observability
which aims to collect the end-to-end time taken by a call.
Changes made to support this -
1) A global interceptor factory registration is created for stats
plugins.
2) OpenCensus plugin now provides a new interceptor that's responsible
for collecting the new latency.
3) Gcp Observability registers this plugin.
4) A new OpenCensus measurement and view is created for api latency.
Note that this is internal as of now, since it's not clear if it should
be exposed as public experimental API. Leaving that decision for the
future.

This PR adds annotations to client attempt spans and server spans on
messages of the form -
* `Send message: 1026 bytes`
* `Send compressed message: 31 bytes` (if message was compressed)
* `Received message: 31 bytes`
* `Received decompressed message: 1026 bytes` (if message needed to be
decompressed)
Note that the compressed and decompressed annotations are not present if
compression/decompression was not performed.

This filter was originally written only for the C++ wrapped layer, but
we have plans to use this for Python (and maybe other wrapped languages
too in the future.)

For stats, the StackDriver/OpenCensus API allows setting the
MonitoredResource directly, so use that.
For tracing, there is no explicit MonitoredResource to use, so just
insert it into the attributes for a span.

This code is not plumbed through yet, but it provides the core
infrastructure needed to detect the proper GCP environment resources
needed to set up the labels/attributes/resources for stats, tracing and
logging.
Details on how the various environment resources are setup has been
derived by looking at java's cloud logging library and OpenTelemetry's
future plans. (Could be better explained in an offline review since some
links are internal).
Requesting @veblush for a full review and @markdroth for a structural
review.

Based on a handful of https://abseil.io/tips, it's generally advised to
only fully-qualify namespaces when in a `using` statement, or when it's
otherwise required for compilation. In all other cases, the general
recommendation is to not fully-qualify.
This change fixes most `grpc.*` namespace uses. There are potential
challenges in trying to make blanket changes to non-gRPC namespace uses,
such as `::testing`, since there is also a `grpc::testing` namespace.

Bazel builds of test/cpp/end2end:end2end_test were failing on Mac OS with v1.8.0 due to missing gtest symbols. The issue is not seen in v1.8.1. A WORKSPACE file was added to gtest repo in 1.8.1, so gtest.BUILD can be removed.
