[pre-commit] Add initial pre-commit config

This change adds configuration for the pre-commit tool,
follow-up changes will address the remaining issues in a phased
approach to make the reviews simpler.

This is based on the pre-commit config used in nova
with some additional hooks.

Follow-up changes will address the FIXME comments
related to sphinx-lint and codespell, as well as update tox
to enforce these checks in ci.
