Kevin Benton 3b02d00591 Enables BigSwitch/Restproxy ML2 VLAN driver
Refactors Bigswitch/Restproxy plugin by separating into
reusable libraries that can be used by the plugin as well
as the ml2 driver to proxy calls to the backend controller.

Enables basic unit tests for the ML2 driver.

Removes deprecated separate unplug/plug operations on ports.

Implements: blueprint bigswitch-ml2-driver
