    Run bashate via pre-commit

    Migrates bashate linting task to pre-commit in order to allow fast
    and transparent execution before uploading changes to gerrit.

    Other linters can be run as well, including flake8 and ansible-linter.
    This also lowers the footprint on developer machines because each
    linter/version is stored only once on disk, regardless how many
    repositories are using it.

    Only action needed for enabling pre-commit as a developer is to
    run `pip install pre-commit`, everything else is done transparently
    after.
