Initial qpid development work

* Switch base tower devel image from u14.04 to c7
* Switch container image to build python dependencies into itself
  instead of forcing it to be built on startup
* Upgrade venv pip to 8.1.2
* Neuter queue.py which was heavily tied to redis and was basically
  orphaned code
* Alter local_settings to override default cache settings and use
  memcached
* Alter local settings to refer to qpid instead of redis for celery
  broker
* Purge redis python dependencies and add qpid and memcached
* Update docker-compose to purge redis and add qpid and memcached
