find a way to test fqdns and shortnames

[jschmid1]

Description of Issue/Question

We have several places in the code that may(some will) behave differently depending on whether salt returns a FQDN or a shortname.

In our testing environemnt(vagrant) we only use shortnames. The CI we are using (openstack with teuthology) shortnames are the standard aswell.

We need to find a way to test shortname && fqdns

I would even put FQDN "higher" in the prio as shortnames as it is best practice to use FQDNs where ever possible.

In case of your testing enhancements also make sure to test "deep / multilevel" FQDNs i.e. server1.room1.location1.datacenter1.company. and servers in the same cluster using different DNS zones - i.e. server1.room1.location1.datacenter1.company. in the same cluster as server12.room7.location2.datacenter2.company.
