Support linting, formatting, etc through pre-commit

[paw-lu]

Background

It's become pretty popular to use .pre-commit-config.yaml to define linting, type-checking, and autoformatting dependencies and processes in Python projects. Many projects go as far as to no longer specify flake8 dependencies in their requirements.txt/pyproject.tom/setup.py.

Unfortunately, it seems vscode-python does not play well with pre-commit.

When cloning a project, the most reliable approach I've found it to

1. Parse the .pre-commit-config.yml for dependencies
2. Manually create an environment with the linting dependencies
3. Add the environment path manually to python.linting.pylintPath.

If anyone has a better workflow, I'd love to know!

Proposal

Support pre-commit as a linter, formatter, and type checker. Adding pre-commit as one of these would use pre-commit run to run the appropriate linting steps (e.g. pre-commit run flake8 --files).

Thanks for the project, I've really enjoyed the Python plugin!
