Have added the required client, server, proto and proto generated files.
The design of the example is as follows:
1. The client sends a bulk amount of data(approx. 2 KB in each
iteration) to the server in a streaming call.
2. The server applies back-pressure by delaying reading of the requests,
which makes the client pause sending requests after around 64KB
3. The client then resumes sending requests only after the server reads
a few requests and clears the buffer.
By adding print statements on data send/receive on both client and
server side, the client pausing/resuming requests can be seen clearly.
The client and server logs can be seen below:

Add registered method change to sync stack server.
## Note
* We're keeping both generic and registered handler in generated stubs (`*_pb2_grpc.py`) because registered method flow is not implemented in aysncio yet, since the stub is used for both sync and asyncio, we can't remove generic method flow until we fully implement the registered method flow in asyncio.

The stubs generated by grpcio_tools should always be used with [the same or higher version of grpcio](https://github.com/grpc/grpc/blob/master/tools/distrib/python/grpcio_tools/setup.py#L313), this change will add a run time check for this requirement inside the generated stubs and therefor enforce this requirement.
Please note for now we're just printing a warning for incorrect usage, we'll **change it to an error** soon.
Example warning message:
```
/usr/local/google/home/xuanwn/workspace/misc/grpc/examples/python/helloworld/helloworld_pb2_grpc.py:21: RuntimeWarning: The grpc package installed is at version 1.60.1, but the generated code in helloworld_pb2_grpc.py depends on grpcio>=1.63.0.dev0. Please upgrade your grpc module to grpcio>=1.63.0.dev0 or downgrade your generated code using grpcio-tools<=1.60.1. This warning will become an error in 1.64.0, scheduled for release on May 14,2024.

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.

- 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`.
### 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.
