New VDU model proposal

VDU model design by using TOSCA composition

Difference between Internal VL and external VL for a VNF External VL for a VNF (defined in IFA 014, the connection between VNFs) Internal VL for a VNF (defined in IFA 011, the connection between VDUs) The definitions of External VL and internal VL in ETSI NFV are different, it is more appropriate to define separate capabilities for External VL and internal VL.
