* Drop ZMQ as the communication mechanism between job_event_callback and
callback_receiver
* Setup queue and exchange for callback broker communication
* Refactor event plugin and callback receiver to efficiently handle
message submission and processing
* Integrate django caching for parent processing
* Meant to be a starting point to more efficiently manage work routing
and to balance work across all tower nodes
* Integrate flower as a dev tool that starts alongside other nodes.
Helpful for observing and monitoring the queues/exchanges

sure if this is needed)
* Define queues and routes for all task work
* Bump celery version to 3.1.23
* Expose flower through haproxy
* Gut the HA middleware
* Purge concept of primary and secondary.
* UUID is not the primary host identifier, now it's based mostly on the
username. Some work probably still left to do to make sure this is
legit. Also removed unique constraint from the uuid field. This
might become the cluster ident now... or it may just deprecate
* No more secondary -> primary redirection
* Initial revision of /api/v1/ping
* Revise and gut tower-manage register_instance
* Rename awx/main/socket.py to awx/main/socket_queue.py to prevent
conflict with the "socket" module from python base

needed anymore
