Initial Gluon Code

This commit contains the first semi-working version of the code to use 
the ML2 plugin wrapper class (GluonPlugin).

Previous repositories contained a standalone Gluon service. This has 
been deprecated and its functionality is now in the GluonPlugin class.

Implements: blueprint gluon-ml2-plugin
