Provide a public experimental API and bazel compatible build target for OpenTelemetry metrics.
Details -
* New `OpenTelemetryPluginBuilder` class that provides the API specified in https://github.com/grpc/proposal/blob/master/A66-otel-stats.md
* The existing `grpc::internal::OpenTelemetryPluginBuilder` class is moved to `grpc::internal::OpenTelemetryPluginBuilderImpl` for disambiguation.
* Renamed `OTel` in some instances to `OpenTelemetry` for consistency.
Closes#35348

Add the flag `enable_csm_observability` to the c++ PSM interop testing
image, such that when enabled from the PSM interop testing framework,
the C++ client/server app will enable the CSM Observability plugin.
* Refactor end2end tests to exercise each EventEngine
* fix incorrect bazel_only exclusions
* Automated change: Fix sanity tests
* microbenchmark fix
* sanitize, fix iOS flub
* Automated change: Fix sanity tests
* iOS fix
* reviewer feedback
* first pass at excluding EventEngine test expansion
Also caught a few cases where we should not test pollers, but should
test all engines. And two cases where we likely shouldn't be testing
either product.
* end2end fuzzers to be fuzzed differently via EventEngine.
* sanitize
* reviewer feedback
* remove misleading comment
* reviewer feedback: comments
* EE test_init needs to play with our build system
* fix golden file test runner

Code used absl::string_view to point into FLAG_xxx, when we changed
to uses absl::GetFlag, absl::string_view is pointing into temp variables
which results in undefined behaviour for the flags.
This replaces gflags. Added TODOs where use of `absl::Duration` or `absl::FlagSaver` might be preferred in follow-up cleanup. Fixes#24493.
This reverts commit da66b7d14e.
NEW:
* Adds references to `absl/flags/declare.h`, new to LTS 2020923.2 imported in commit 5b43440.
* Works around MSVC 2017 compiler error with large help text on flags by reducing the help text.
fixes two bugs with the client, with an uninitialized int and where the
"timer" used to approximate a QPS would block waiting for a synchronous
RPC to timeout, which dramatically limited the QPS.
