* Add inisghts fact scan module
* Update fact scan playbook to call new insight fact scan module
* JT run w/ store_facts=True will save scanned facts. We "skim" the
machine_id fact from Insights fact scans and associate it with the host
that the fact scan came from.
* Remove system tracking piggybacked most-recent-fact-gathering
* Add explicit per-jobtemplate configurable fact gathering
* Continue to support system tracking
* Fixed a bug where we weren't ack()ing system tracking rabbit msgs
* 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
* Revist/gut the Instance manager... not sure if this manager is really
needed anymore
* awx.main.models Fact added
* view host fact and timeline updated to use new Postgres Fact model instead of Mongo
* Removed license set start Mongo logic
* added View tests
* added Model tests
* Removed mongo fact unit tests
* point at modified jsonbfield that supports sqlite storage driver
* postgresify fact cache receiver
* test OPTIONS endpoint
* Note: single fact view not implemented yet.
Optionally allow processing of fact receiver messages in a worker
thread. This works around an issue where data could take a while to
page into Mongo and cross the zmq socket timeout.
* added mongo connection logic
* added mongo dbtransform logic to allow keys with . and $
* altered tower fact scanner CacheModule to emit a message for each fact module facts (including ansible facts). Previously, seperate facts module facts were getting concatenated to each subsequent emi
* tower fact scanner CacheModule timeout set as to not hang for forever
* broke apart commands.py test
* added unit test for run_fact_cache_receiver, facts, and dbtransform
