L2 Model additions to support DVR

This patch introduces the models, the DB migrations
and the config options required by the L2 layer to
support DVR east/west traffic.

These changes will be used by the control-plane made
of ML2, L2pop and L2 agent.

Two new configuration options have been introduced:
'dvr_base_mac' is used to set DVR MAC addresses apart
from tenant ones (every distributed router will have
ports being created on compute hosts) and
'enable_distributed_routing' is used to enable dvr
support in the L2 agent. This gives the capability of
rolling out the dvr functionality in stages.
