Working towards testing against CSM Observability. Added ability to
register a prometheus exporter with our Opentelemetry plugin. This will
allow our metrics to be available at the standard prometheus port
`:9464`.
Third try for #32466.
This adds an interop client / server for GCP Observability integration
testing.
Everything is new here with no refactor. Plan is to get this in first
before trying to refactor out the flags.
Refactor C++ interop test client flags into the common
`client_helper.h/cc`. This is needed by the observability testing PR
#32466
We need the `ABSL_DECLARE_FLAG` in the header file so that we can share
that across different implementation.
* 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

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.
This is for compatibility with IPv6-only environments; see the Google
bug b/32531998.
Note that InteropClient.cs and http2_client.cc don't appear to be tested
by our internal branch, but I've included them for consistency.
