    Tag the alembic migration revisions for Liberty

    Previously when we had one repo with one alembic branch we would
    create a milestone revision on that single branch. Now we have
    multiple repos and expand/contract branches for each repo.

    So from now on we tag the final revision on every branch when we make
    a milestone release. Update the cli to support the command:
      neutron-db-manage upgrade <milestone>
    where <milestone> becomes an alias for all the revisions for a
    milestone.
