Subject: cluster: If hostname doesn't contain the domain, try to derive this from FQDN
Patch-mainline: Not yet
Git-commit: fc9adfb41ba29d83fe083248e17c3a2d03d76e16
References:

SUSE doesn't include the domainname in the hostname. One may still
set the domain name using DNS or /etc/hosts.
Call 'hostname -f' to get the FQDN and try to separate the domain
part from it.
