Multicast group limit

This task is a security test that checks that a customer can only join a specified maximum number of multicast channels. If the customer attempts to join one more channel, then either the join should be ignored, or some channel previously joined should be disabled.

The task also checks that within the above limitation, the customer can receive the desired multicast channels without problems.

This task requires an external multicast source and works only with IPv4.
