If we start cinderlib from the N release with the DBMS persistence plugin on a DB where we have already run it with release N+1 then we'll get an `oslo_db.exception.DBMigrationError` exception. This is because cinderlib automatically does a `db_sync` on each initialization, but on N this will fail because there will be unknown (as in newer) migrations applied to the DB. This patch takes this possibility and checks the exception raised by `db_sync` and ignores it if the `migrate` package complains with a VersionNotFoundError.
