VNF Node Template Metadata Section(s)
Used in order for an Operational Policy to take an action on a specific VNF. For Scale Out, this depends on the target type specified in the Control Loop event from DCAE.

CLAMP should parse the "group" section and select only VF Modules that have a property isBase=false in order to do Scale Out.
