CORD-348 multicast support in SegmentRouting and vRouter 

In this submission:
* Setup/teardown multicast route according to SinkAdded/SinkRemoved event
    - ingressVlan and egressVlan is configurable through network config
* Change behavior of OFDPA VLAN assignment
    - Always use the VLAN in metadata if present
* Bugfix of writing immutable object

NOT in this submission (coming soon):
* Error handling (e.g. link/device failure recovery)
