Markus Lehtonen 3b9bc575bc Change ExecuteGroupRule to return detailed result 
Modify the ExecuteGroupRule() which is used for NodeFeatureGroups to
return detailed match status, similar to the Execute (used for
NodeFeatureRules). This prepares for using the simpler GroupRule type in
the image compatibility API.
