Stephen Finucane eb728e877a db: Final cleanups
Some things that were missed in previous patches and are thrown together
here:

- Add alembic as an explicit dependency (we were getting it transitively
  from oslo.db). We also bump the sqlalchemy dependency to a 1.4.x
  release, which is the minimum supported by our chosen version of
  alembic (more on this below)
- Remove tooling related to the old migrations
- Fix the tox whitelisting of the flaky MySQL tests

On the SQLAlchemy front, we opt for 1.4.13. Technically alembic should
support anything from 1.4.0, however, with SQLAlchemy >= 1.4.0, < 1.4.13
we see errors like the following in some tests:

  sqlalchemy.exc.InvalidRequestError: Entity namespace for
  "count(instance_mappings.id)" has no property "queued_for_delete"

There's nothing specific about this in the release notes for 1.4.13 [1]
but it definitely fixes things.
