Oier Bravo Urtasun c7151b7333 fix(mdns): publish via host avahi over D-Bus (not a second daemon) ...

A container running its own avahi-daemon collides with the host's on :5353.
Instead publish to the host avahi over its mounted D-Bus socket using avahi-tools
(avahi-publish). Needs apparmor=unconfined (docker-default blocks the D-Bus
publish). Documented host prereqs incl. allow-interfaces for multi-bridge hosts.

Tested: publish reaches host avahi and registers the names; on hosts with many
docker bridges avahi self-collides until restricted to the LAN interface.
