If the new variable systemd_resolved is defined, resolved will be setup
within the environment. This will configure the global configuration
file and restart the service.
A test has been added to ensure this code path is exercised on every
commit. It should be noted that suse does not have a resolved package so
this functionality is disabled when a suse system is encountered. This
should be revised as soon as suse has resolved available.
