* Update docs/submodules/pharos from branch 'master'
  - Merge "Add Dashboard Listener"
  - Add Dashboard Listener

    JIRA: N/A

    Adds source/pharos.py, which will periodically poll the paros
    dashboard api to see if any new bookings have started on and of your
    dev pods. If a new booking is starting, a deployment will be
    started for that pod.

    source/listen.py starts the pharos listener in a background
    process, so that it will not eat your terminal.
