Fixes NFV VNFFG and groups

Fixes Include:
 - nfv.VNFFG type does not include "targets" in its properties in the
   TOSCA NFV spec.  The usage of "targets" should actually be "members"
   which is defined in the core group.Root definition.
 - Removes vnf.VNFFG requirements which are not part of the spec.
 - Fixes reference to TARGETS in groups.py SECTIONS
