might make sense to either use '-' or 'Standalone node' as fallback 
here? both variants would be easily parsable as 'not a cluster name' ;)

depending on the exact template an empty variable resolution can read 
quite weird/confusing.

e.g.

  Cluster {cluster}
  {guestname}

and a quick glance would imply we are on a cluster called like the guest 
;)
