Pacemaker doesn't allow grouping cloned resources. It is possible to 
clone a group of resources, though.

Allowed relations are:
- Group can contain one or more primitive resources, empty groups are 
not allowed
- Clone can contain one group or one primitive resource, empty clones 
are not allowed
