PBB EVPN changes

Changes included:
1. Schema changes to make bridge-domain as child of virtua-network

2. Don't allow VMI to refer to different bridge domain for same vlan tag.
e.g. Say, VMI refers to BD1 for vlan tag 0, don't allow this VMI to refer to
another bridge domain(BD2) for vlan tag 0.

3. Add Unit test case for restricting VMI link to single bridge-domain
for a given vlan tag
