VXLAN multicast dst (remote) address support
Added support for multicast vxlan tunnels which are used for bridge domain flooding instead
of flooding the all unicast tunnels in the bridge domain.
features added:
* conditional flooding to some of the BD members - based on existance of multicast tunnel member
* added local multicast adjacency - multicast packets are handled as the same as unicast - based on src (unicast) address
* refactored some of vxlan tunnel creation code - to unify ip4/6 handling
