Run mypy from tox

This avoids the need to duplicate our dependency list in multiple
places and allows us to take advantage of tox's dependency management
infrastructure, to ensure we always get the latest and greatest version
of a package allowed by upper-constraints.

While here, we also update versions of other pre-commit hooks and
simplify the mypy configuration, aligning it with that of other typed
oslo projects.
