Code Issues Proposed changes

Make DVR router support FLAT network for ovs-agent 

Currently codes only support assocate tunnel network and vlan network
to DVR router. This patch add codes that make the flat network assocate
to DVR router and make it work fine.

The patch also remove two unused constant entries: 'FLAT_VLAN_ID' and
'LOCAL_VLAN_ID'

``DVR`` routers now support ``flat`` networks.
fixes:
- |
Fixed bug `1876092 <https://bugs.launchpad.net/neutron/+bug/1876092>`_
which caused DUP ICMP replies on the ``flat`` networks used with ``DVR``
routers.
