The change simply adds a more complete hostname within the
"/etc/hosts" file for all nodes within inventory which
ensures all hosts are reachable and have a proper host entry
for itself and all other hosts. Additionally the hostname
insert script has been made idempotent and tests have been
added to ensure functionality.
