Based on [OpenTelemetry Metrics gRFC](https://github.com/grpc/proposal/blob/master/A66-otel-stats.md#opentelemetry-metrics), we should recored unregistered RPC method name as `other`, this PR adds the ability to pass register method information when creating a call.
We'll consider calls created using generated stubs as registered, note that this won't prevent user from setting `registered_method=True` when creating calls manually.
This is also enabled for simple stub flow but **NOT enabled for AsyncIO**, we'll add that later when start working on AsyncIO Observability.

This change is part of a migration of the Node examples from this
repository to the grpc/grpc-node repository, along with
grpc/grpc-node#2474. I replaced the files with references to the new
location instead of deleting them so that people following links in
existing external resources would find information about the new
location instead of an unhelpful 404 error. I discovered that even some
of the individual `.js` files are linked from other places, so to be
safe I performed this replacement on every file in the directory.
- Switched from yapf to black
- Reconfigure isort for black
- Resolve black/pylint idiosyncrasies
Note: I used `--experimental-string-processing` because black was
producing "implicit string concatenation", similar to what described
here: https://github.com/psf/black/issues/1837. While currently this
feature is experimental, it will be enabled by default:
https://github.com/psf/black/issues/2188. After running black with the
new string processing so that the generated code merges these `"hello" "
world"` strings concatenations, then I removed
`--experimental-string-processing` for stability, and regenerated the
code again.
To the reviewer: don't even try to open "Files Changed" tab 😄 It's
better to review commit-by-commit, and ignore `run black and isort`.

This is nearly identical to the helloworld example's greeter callback
server, but without the health check service enabled. Having a separate
example for reflection may help folks find this code.
### Description
Fix https://github.com/grpc/grpc/issues/24470.
Adding one example which demonstrate the following use cases:
* Generate RPC ID on client side and propagate to server.
* Context propagation from client to server.
* Context propagation between different server interceptors and the
server handler.
## Use:
1. Start server: `python3 -m async_greeter_server_with_interceptor`
2. Start client: `python3 -m async_greeter_client`
### Expected Logs:
* On client side:
```
Sending request with rpc id: 73bb98beff10c2dd7b9f2252a1e2039e
Greeter client received: Hello, you!
```
* On server side:
```
INFO:root:Starting server on [::]:50051
INFO:root:Interceptor1 called with rpc_id: default
INFO:root:Interceptor2 called with rpc_id: Interceptor1-default
INFO:root:Handle rpc with id Interceptor2-Interceptor1-73bb98beff10c2dd7b9f2252a1e2039e in server handler.
```

The very non-trivial upgrade of third_party/protobuf to 22.x
This PR strives to be as small as possible and many changes that were
compatible with protobuf 21.x and didn't have to be merged atomically
with the upgrade were already merged.
Due to the complexity of the upgrade, this PR wasn't created
automatically by a tool, but manually. Subsequent upgraded of
third_party/protobuf with our OSS release script should work again once
this change is merged.
This is best reviewed commit-by-commit, I tried to group changes in
logical areas.
Notable changes:
- the upgrade of third_party/protobuf submodule, the bazel protobuf
dependency itself
- upgrade of UPB dependency to 22.x (in the past, we used to always
upgrade upb to "main", but upb now has release branch as well). UPB
needs to be upgraded atomically with protobuf since there's a de-facto
circular dependency (new protobuf depends on new upb, which depends on
new protobuf for codegen).
- some protobuf and upb bazel rules are now aliases, so `
extract_metadata_from_bazel_xml.py` and `gen_upb_api_from_bazel_xml.py`
had to be modified to be able to follow aliases and reach the actual
aliased targets.
- some protobuf public headers were renamed, so especially
`src/compiler` needed to be updated to use the new headers.
- protobuf and upb now both depend on utf8_range project, so since we
bundle upb with grpc in some languages, we now have to bundle utf8_range
as well (hence changes in build for python, PHP, objC, cmake etc).
- protoc now depends on absl and utf8_range (previously protobuf had
absl dependency, but not for the codegen part), so python's
make_grpcio_tools.py required partial rewrite to be able to handle those
dependencies in the grpcio_tools build.
- many updates and fixes required for C++ distribtests (currently they
all pass, but we'll probably need to follow up, make protobuf's and
grpc's handling of dependencies more aligned and revisit the
distribtests)
- bunch of other changes mostly due to overhaul of protobuf's and upb's
internal build layout.
TODOs:
- [DONE] make sure IWYU and clang_tidy_code pass
- create a list of followups (e.g. work to reenable the few tests I had
to disable and to remove workaround I had to use)
- [DONE in cl/523706129] figure out problem(s) with internal import

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.

Adds a simple hello-world example for GCP Observability purposes along
with a README.
The microservices observability user guide is not yet up, but this still
refers to it anyway.

1. All greeter servers now support flag `--port` to customize the listen
port.
2. All client implementation now have `--target` flag to specify the
server location.
3. ABSL is used to parse the flags to reduce the amount of boilerplate
code in the examples.
