Bug Description

If num_engine_workers larger than 1 , restart senlin-engine might get following warnings occasionally:

/home/stack/huyanyan/python/virtualenv/SENLINENV/lib/python2.7/site-packages/sqlalchemy/orm/persistence.py:925: SAWarning: DELETE statement on table 'service' expected to delete 1 row(s); 0 were matched. Please set confirm_deleted_rows=False within the mapper configuration to prevent this warning.

There might be potential race condition during cleaning dead service records in db.
