[grpc][Gpr_To_Absl_Logging] Migrating from gpr to absl logging - gpr_log
In this CL we are migrating from gRPCs own gpr logging mechanism to absl logging mechanism. The intention is to deprecate gpr_log in the future.
We have the following mapping
1. gpr_log(GPR_INFO,...) -> LOG(INFO)
2. gpr_log(GPR_ERROR,...) -> LOG(ERROR)
3. gpr_log(GPR_DEBUG,...) -> VLOG(2)
Reviewers need to check :
1. If the above mapping is correct.
2. The content of the log is as before.
gpr_log format strings did not use string_view or std::string . absl LOG accepts these. So there will be some elimination of string_view and std::string related conversions. This is expected.

[grpc][Gpr_To_Absl_Logging] Migrating from gpr to absl logging GPR_ASSERT
Replacing GPR_ASSERT with absl CHECK
Will not be replacing CHECK with CHECK_EQ , CHECK_NE etc because there are too many callsites. Only a few - which fit into single - line regex will be changed. This would be small in number just to reduce the load later.
Replacing CHECK with CHECK_EQ , CHECK_NE etc could be done using Cider-V once these changes are submitted if we want to clean up later. Given that we have 5000+ instances of GPR_ASSERT to edit, Doing it manually is too much work for both the author and reviewer.

This is a big rewrite of global config.
It does a few things, all somewhat intertwined:
1. centralize the list of configuration we have to a yaml file that can
be parsed, and code generated from it
2. add an initialization and a reset stage so that config vars can be
centrally accessed very quickly without the need for caching them
3. makes the syntax more C++ like (less macros!)
4. (optionally) adds absl flags to the OSS build
This first round of changes is intended to keep the system where it is
without major changes. We pick up absl flags to match internal code and
remove one point of deviation - but importantly continue to read from
the environment variables. In doing so we don't force absl flags on our
customers - it's possible to configure grpc without the flags - but
instead allow users that do use absl flags to configure grpc using that
mechanism. Importantly this lets internal customers configure grpc the
same everywhere.
Future changes along this path will be two-fold:
1. Move documentation generation into the code generation step, so that
within the source of truth yaml file we can find all documentation and
data about a configuration knob - eliminating the chance of forgetting
to document something in all the right places.
2. Provide fuzzing over configurations. Currently most config variables
get stashed in static constants across the codebase. To fuzz over these
we'd need a way to reset those cached values between fuzzing rounds,
something that is terrifically difficult right now, but with these
changes should simply be a reset on `ConfigVars`.

* 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

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.

More generic configuration system is introduced in order to i) unify the
way how modules access the configurations instead of using low-level
get/setenv functions and ii) enable the customization for where configuration
is stored. This could be extended to support flag, file, etc.
Default configuration system uses environment variables as before so
basically this is expected to work just as it did. This behavior can
change by redefining GPR_GLOBAL_CONFIG_DEFINE_*type* macros.
