Sergii Tkachenko de6ed9ba9f [Python] Migrate from yapf to black (#33138 )

- 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`.

Retry Example in gRPC Python

Prerequisite

grpcio >= 1.39.0
grpcio-tools >= 1.39.0

Running the example

In terminal 1, start the flaky server:

python3 flaky_server.py

In terminal 2, start the retry clients:

python3 retry_client.py
# Or
python3 async_retry_client.py

Expect results

The client RPC will succeed, even with server injecting multiple errors. Here is an example server log:
