  - Supporting PNFD (SOL001) mapping to Internal AID model

    This maps the PNF descriptor containing etsi defined types
    according to SOL001 v2.5.1 to openecomp internal model. The
    transformation is done in the "Create VSP" stage. As the main
    PNF type gets mapped to the outer container in internal ecomp
    model, it is possible to have no "resource instances" when
    importing the PNF model into the catalog. The code was updated
    to allow this for PNFs.
