Barbican is using Celery to interface to the HA queues it uses to send asynchronous requests from API nodes to the worker nodes. This change request replaces Celery with OpenStack-friendly oslo.messaging RPC components. Change-Id: Ibc257e98726938a577da4300b389fa13ff34d8a0 Implements: blueprint queue-use-oslo-messaging
