This error can trigger for either initial or trailing metadata (and
we've had outages where the latter was the cause).
I don't think we know at this layer if we're parsing initial or trailing
- though it'd be a good exercise to plumb that through.
For now remove the word initial because it's better to give less
information than wrong information.

This reverts commit 4b46dbc19e.
Reason: this seems to be breaking load reports in certain cases,
b/276944116
Let's revert so this doesn't accidentally get released.
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.

Notes:
- `+trace` fixtures haven't run since 2016, so they're disabled for now
(7ad2d0b463 (diff-780fce7267c34170c1d0ea15cc9f65a7f4b79fefe955d185c44e8b3251cf9e38R76))
- all current fixtures define `FEATURE_MASK_SUPPORTS_AUTHORITY_HEADER`
and hence `authority_not_supported` has not been run in years - deleted
- bad_hostname similarly hasn't been triggered in a long while, so
deleted
- load_reporting_hook has never been enabled, so deleted
(f23fb4cf31/test/core/end2end/generate_tests.bzl (L145-L148))
- filter_latency & filter_status_code rely on global variables and so
don't convert particularly cleanly - and their value seems marginal, so
deleted

This PR also centralizes the client channel resolver selection. Resolver
selection is still done using the plugin system, but when the Ares and
native client channel resolvers go away, we can consider bootstrapping
this differently.
This commit adds support for using CIDR blocks defined in the `no_proxy`
environment variable. For example:
```
http_proxy=http://localhost:8080 no_proxy=10.10.0.0/24
```
The example above would bypass the proxy if the server IP matched
10.10.0.0 - 10.10.0.255.
Closes#22681

The logic is straightforward: attempt to read the
`GRPC_ALTS_MAX_CONCURRENT_HANDSHAKES` environment variable and, if it
set to an integer, instantiate the handshake queues based on this
integer.
Based on go/grpc-alts-concurrent-handshake-cap.

Implement listeners, connection, endpoints for `FuzzingEventEngine`.
Allows the fuzzer to select write sizes and delays, connection delays,
and port assignments.
I made a few modifications to the test suite to admit this event engine
to pass the client & server tests:
1. the test factories return shared_ptr<> to admit us to return the same
event engine for both the oracle and the implementation - necessary
because FuzzingEventEngine forms a closed world of addresses & ports.
2. removed the WaitForSingleOwner calls - these seem unnecessary, and we
don't ask our users to do this - tested existing linux tests 1000x
across debug, asan, tsan with this change
Additionally, the event engine overrides the global port picker logic so
that port assignments are made by the fuzzer too.
This PR is a step along a longer journey, and has some outstanding
brethren PR's, and some follow-up work:
* #32603 will convert all the core e2e tests into a more malleable form
* we'll then use #32667 to turn all of these into fuzzers
* finally we'll integrate this into that work and turn all core e2e
tests into fuzzers over timer & callback reorderings and io
size/spacings

(hopefully last try)
Add new channel arg GRPC_ARG_ABSOLUTE_MAX_METADATA_SIZE as hard limit
for metadata. Change GRPC_ARG_MAX_METADATA_SIZE to be a soft limit.
Behavior is as follows:
Hard limit
(1) if hard limit is explicitly set, this will be used.
(2) if hard limit is not explicitly set, maximum of default and soft
limit * 1.25 (if soft limit is set) will be used.
Soft limit
(1) if soft limit is explicitly set, this will be used.
(2) if soft limit is not explicitly set, maximum of default and hard
limit * 0.8 (if hard limit is set) will be used.
Requests between soft and hard limit will be rejected randomly, requests
above hard limit will be rejected.

Previously we triggered a flow control update when `announced <
target/2`, but if `target==1` then we fail to send a flow control update
(announced is never less than 1/2==0) and break our forward progress
guarantees.

actually calls for UUIDv4.

This allows us to replace `absl::optional<TaskHandle>` with checks
against the invalid handle.
This PR also replaces the differently-named invalid handle instances
with a uniform way of accessing static invalid instances across all
handle types, which aids a bit in testing.
Add an event manager that spawns threads just as much as it possibly
can... to expose TSAN to the myriad thread ordering problems in our code
base.
Next steps for this will be to add a new test mode for tsan + thready
event engine + a few other doodads to increase threads in the system
(party.cc in particular has a good place for a hook).

(part of removing support for VS2017)
Also see https://github.com/grpc/grpc/pull/32649
Also see https://github.com/grpc/grpc/pull/32615
The switch to grpc-win2019 windows workers has already happened:
(cl/517400022).
Once this PR lands, I'll backport to 1.53.x branch as well (since that
release removes the VS2017 support).
This PR is a small code change with a lot of new test data.
[In OpenSSL, there are two flags that configure CRL checks. Coping
relevant
section:](https://www.openssl.org/docs/man1.0.2/man3/X509_VERIFY_PARAM_get_depth.html)
> - X509_V_FLAG_CRL_CHECK enables CRL checking for the certificate chain
leaf certificate. An error occurs if a suitable CRL cannot be found.
> - X509_V_FLAG_CRL_CHECK_ALL enables CRL checking for the entire
certificate chain.
We currently only set `X509_V_FLAG_CRL_CHECK`, so we will only ever
check if the leaf certificate is revoked. We should check the whole
chain. I am open to making this a user configuration if we want to do it
that way, but we certainly need to be able to check the whole chain.
So, this PR contains the small code change in
`ssl_transport_security.cc` to use the `X509_V_FLAG_CRL_CHECK_ALL` flag.
Then the rest of the changes are in tests. I've added all the necessary
files to have a chain built that looks as follows
`Root CA -> Revoked Intermediate CA -> Leaf Certificate`, and added a
test for this case as well.
You can verify that on master this new test will fail (i.e. the
handshake will succeed even though the intermediate CA is revoked) by
checking out this branch, running `git checkout master --
./src/core/tsi/ssl_transport_security.cc`, then running the test.
I also slightly reorganized test/core/tsi/test_creds/ so that the CRLs
are in their own directory, which is the way our API intends to accept
CRLs.
Fixing TSAN data races of the kind -
https://source.cloud.google.com/results/invocations/c3f02253-0d0b-44e6-917d-07e4bc0d3d62/targets/%2F%2Ftest%2Fcpp%2Fperformance:writes_per_rpc_test@poller%3Dpoll/log
I think the original issue was the non-atomic load in
writes_per_rpc_test.cc but also making the change to use barriers
instead of relaxed atomics (probably unimportant but I'll prefer safety
in the absence of otherwise comments).
Could probably also use std::atomic but feeling a bit lazy to make the
changes throughout.

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.
