[udp]: Add property to allow multicast sockets to be bound to multicast addresses
Submitted by Patricia Muscalu
It should be possible to configure the multicast sockets to be bound to multicast addresses, e.g. in situations when it's desired that the traffic received on the socket is restricted to the multicast traffic only.
