consolidate pytest config in pyproject.toml

[jameslamb]

fixes #6194

Wheel tests in this project are emitting tons of warnings like this:

test_random_forest.py:1247
/__w/cuml/cuml/python/cuml/cuml/tests/test_random_forest.py:1247: PytestUnknownMarkWarning: Unknown pytest.mark.memleak - is this a typo? You can register custom marks to avoid this warning - for details, see https://docs.pytest.org/en/stable/how-to/mark.html
@pytest.mark.memleak

I think that's because the introduction of a pytest.ini file in #6078 resulted in all of the pytest options from pyproject.toml being ignored.

From https://docs.pytest.org/en/stable/reference/customize.html#pytest-ini

pytest.ini files take precedence over other files, even when empty.

I think "take precedence" there means that if pytest finds a pytest.ini, it stops searching for other configuration files.

/ok to test

Thanks for taking the time to figure this out and then fix it straight away.

Looks good to me.

Annoying that we can't add a pytest.ini with a warning for people from the future to not use it :-/

@betatim we could add pytest.ini to .gitignore with a comment! Want me to do that?

[betatim]

Good idea!

[jameslamb]

Thanks for considering it! @betatim I just pushed that change, will you take a look and let me know what you think?

I intentionally am leaving python/cuml/cuml/benchmark/automated/pytest.ini because I don't know exactly how it's used in this repo.

I intentionally am leaving python/cuml/cuml/benchmark/automated/pytest.ini because I don't know exactly how it's used in this repo.

I also don't know exactly what it does/when it is used. But the robots (aka CI) seem happy with it in place so I'd also leave it alone for now.

This is blocked by the error reported in #6206, which will hopefully be fixed by #6207

[jameslamb]

updated these rules based on an offline conversation with @vyasr and @dantegd

pyproject.toml-only changes just need packaging-codeowners (handled by the pyproject.toml rule a few lines down).

This change also adds `cuml-cmake-codeowners:

• when any .cmake file is touched
• when any CMakeLists.txt file is touched (regardless of depth in the filesystem)

Looks good to me.

Not sure how to persuade the telemetry job to succeed. Just restarting it doesn't help. From the error message it sounds like it doesn't like being run a lot of time after other jobs it depends on? At least that is my explanation for why the artefact it is trying to download doesn't exist.

I'd merge this as it is without trying to figure that one out. Assuming the optional jobs are truly optional (they fail because of #6209 so not something related to this PR)
