fix(controller/supervisord): WIP Supervisord to start deis-controller

Currently the Deis Controller uses a bash file for startup. This doesn't deal with
issues when certain parts of the bash file breaks down. Instead this PR will aim to
work on building a [supervisord](supervisord.org) alternative that can monitor the
processes (maybe using [superlance](http://superlance.readthedocs.org/en/latest/))

This is WIP and requires a lot of feedback. Trying to put together a supervisord.conf
file at first.

Closes #1306
