This change proposes the use of Alembic to manage Glance migrations. * Introduce new directory ``alembic_migrations`` under ``glance/db/sqlalchemy``. This directory is the home for all glance migrations henceforth. All the migration scripts reside under ``versions`` directory. * All the migrations up to Liberty are consolidated into one migration called ``liberty_initial`` as those migrations are not supported any more. Mitaka migrations are retained but under a different naming convention. * All the glance manage db commands are changed appropriately. They now use alembic to perform operations such as ``version``, ``upgrade``, ``sync`` and ``version_control``. * The database versions are not numerical any more. They are the revision ID of the last migration applied on the database. Since we don't support migrations before Mitaka, the Liberty version ``42`` will now appear as ``liberty``. Migration ``43`` and ``44`` in Mitaka appear as ``mitaka01`` and ``mitaka02`` respectively. * When one performs a ``sync`` or ``upgrade`` command, the database is first stamped with an equivalent alembic version before upgrading. * The older migration scripts are retained so that users can correlate with the new migrations. Also, it is probably safe to retain them until the alembic migrations become stable. Similarly, the ``migrate_version`` table is not removed yet.
