Closes#36557
PiperOrigin-RevId: 639073741
New source of truth: https://github.com/grpc/psm-interop.
This PR removes PSM Interop framework source code from `tools/run_tests/xds_k8s_test_driver`, and all references to it.
Closes#35466

- 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`.
* Handle gevent exception in gevent poller
Currently the gevent poller ignores exceptions raised by
`gevent.wait()`, which causes greenlets to be unkilable while waiting.
This change handles exceptions raised while waiting in the gevent
poller, cancels the gRPC call and propagates the error back to the
application.

* Fix imports in header files
* Lint gevent tests
* Set grpc event type to GRPC_QUEUE_SHUTDOWN upon cancel error
To prevent `grpc_completion_queue_next()` to be called indefinitely when
the queue is shut down.
* Remove unnecessary `except *`
* Improve gevent tests
* Format code
* Remove unnecessary import

The test modules were not under pylint jurisdiction,
and actual bugs have been found in tests that would
have been prevented had we run static analysis on
the test code as we do on the core modules.
This is the first step to enable pylint on tests.
Due to numerous warnings since the code is not ready
and needs refactoring, a new `.pylintrc`
specific to tests is added that suppresses a number
of valid warnings. The goal is stepwise elimination
of each class of warning while refactoring the code
such that it will not emit any warnings in future
commits, always keeping the sanity checks passing
and keeping the disruption minimal.
Pylint is only enabled for "grpcio/grpc" package,
and various specific checks that currently fail are disabled,
each with a respective TODO item in the .pylintrc file.
The source code is moved from src/python to
src/python/src. A setup.py is added at
src/python. The build_python.sh and
run_python.sh scripts are updated to build
and run the Python tests by building a
package and installing it in the developer's
Python 2.7 virtual environment.
