Bug Description

I'm observing a new failure in a sqlalchemy migration test as of this morning. Part of our testing would create an oslo_db.sqlalchemy.migration_cli.manager.MigrationManager and call a downgrade/upgrade of relative revisions (for example: manager.downgrade("-1") ). Now I'm observing this throw a "oslo_db.exception.DbMigrationError: Revision does not exist".

It looks as though the downgrade function in oslo_db/sqlalchemy/migration_cli/manager.py looks for an explicit revision id to exist in the revision argument (for a None) and not considering relative revision args like "-1", "+1", ect.
