The Modular L2 Plugin uses drivers to support separately extensible sets of network types and of mechanisms for accessing networks of those types. This is an initial implementation that has been tested with the openvswitch and linuxbridge agents, and should also work with the hyperv agent. See quantum/plugins/ml2/README for details. Implements: blueprint modular-l2 Change-Id: Ia8cae480180f0990af7d5e5e56f29eaeac205e0e
