Initial setup

Initial client utilities-

The primary things I plan to extract out of the docker-worker are 

  - a dumb amqp connection creation util (which fetches credentials from queue)
  - configuration defaults overrides (queue url, etc..)
  - binding exchanges to a queue

Next things I imagine living here are:

  - authentication
  - posting tasks? 
  - any other common things that are TA talking to other TA components
