Description

Use Case

I want to use the socket_listener to join and receive messages from Source-Specific-Multicast (SSM) groups using IGMPv3.

Expected behavior

When the socket_listener is configured with a specific "multicast_source" and a multicast "service_address", I expect telegraf to join the multicast group using IGMPv3 "IP_ADD_SOURCE_MULTICAST".

Actual behavior

Currently telegraf's socket_listener can only join Any-Source-Multicast (ASM) groups using "IP_ADD_MEMBERSHIP". No SSM messages can be received as SSM requires listeners to join using the correct join request.
