CORD-348 Fabric multicast support - error handling 

Automatically failover to backup spine if
- ingress - transit link down
- transit - egress link down
- transit device down

Can recover from fatal error with human involved
- ingress switch down
- egress switch down
- all links to spine down

Scan through McastRouteStore when
- SR activate
- link up

Also include following features
- Use flow objective context in McastHandler
- Update Mcast VLAN config sample
