Some functions in Octavia receive 2 DB session parameter, one is a session in "autocommit" mode, the other without "autocommit" mode. Now that the autocommit feature is removed from sqlalchemy, we can clean up some leftovers of this migration, 2 session objects were passed to these functions (and sometime the same object), only one is needed.
