Add of the Supervisor configuration
I created the Supervisor configuration file. At the moment, the
configuration hasn't been tested because of the incompatibilities of
Supervisor with Python 3. It still needs to be resolved.
The configuration has been copied from Rails and adapted to run a Django
application and later on a Redis cache system (commented at the moment).
