vgchange: Prompt when setting VG cluster attr if cluster is not setup

Browse Source 
If clvmd is not running or the locking type is not clustered and someone
attempts to set the cluster attribute on a volume group, prompt them to
see if they are sure.  (Only prompt for one though.  If neither are true,
simply ask them once.)
