Convert devstack-bashate to native job

Retire the legacy job for an equivalent native job.

Note this drops devstack-gate testing; that runs tox without a
basepython so breaks when we move bashate to Python 3.  bashate is
pinned in devstack-gate to 0.5.0, and devstack-gate is considered
deprecated, so it will not update to a non-supported version.  We
don't need to keep linting it.
