Subject: mdns: T5615: Allow controlling IP version to use for mDNS repeater

This commit adds a new configuration option to the mDNS repeater service
to allow controlling which IP version to use for mDNS repeater.

Additionally, publishing AAAA record over IPv4 and A record over IPv6 is
disabled as suggested.
