This should fix the issue reported on ros2/ros2#1052

Multicast was not correctly being sent through localhost interface when no network interface was detected. This PR changes the mechanism from adding a localhost initial peer to binding the outbound socket to the local interface.

@MiguelCompany MiguelCompany added this to the v2.0.2 milestone Oct 27, 2020

Could you write a regression test using test_UDPv4Transport? This implies implementing a new feature in test_UDPv4Transport: be able to return zero interfaces to Fast-DDS.
