Unstoppable EDP Heartbeat

[advancenXX]

When Participant A creates, device A only has 127.0.0.1.
Then, device B connects to device A, and new network interface comes.
Device A(192.168.42.2) -------- Device B(192.168.42.3)
Participant A(127.0.0.1) -------- Participant B(192.168.42.3)

For some reasons, (maybe other Participant joined multicast group), Participant A can receive B's PDP, and send EDP Heartbeat to B. We can find A's EDP Heartbeat packet from 192.168.42.2 to 192.168.42.3 through wireshark.
The problem is, the Heartbeat could never be acknowledged by B, as B always send acknack to A's 127.0.0.1. Then, A will call send_heartbeat_to_all_readers every 1 second.

    // StatefulWriter.cpp
    unacked_changes = for_matched_readers(readers_,
                    [](ReaderProxy* reader) {
                        return reader->has_unacknowledged();
                    });

    if (unacked_changes) {
        //TODO if separating, here sends periodic for all readers, instead of ones needed it.
        send_heartbeat_to_all_readers();
    }

We do not need A to connect with B, but the EDP Heartbeat can not be stopped.
