Avahi provides local hostname resolution using a "hostname.local" naming scheme.
This ansible role installs the required dependencies and configures the DNS resolver accordingly.
You can opt-out from deploying a new ``/etc/nsswitch.conf`` config by setting ``avahi__configure_nsswitch`` to ``false``.
You can opt-in in a simple versionscheck that can prevent you from running a older version of this role by setting ``submodules_versioncheck`` to ``true``.
