When a service model (CSAR package) contains multiple VNFs, AAI doesn't parse the model correctly. Only one VNF is inventoried under https://aai_ip:aai_port/aai/aai_api_ver/service-design-and-creation/models

Based on some tests, it could be that during model parsing the last VNF listed in the CSAR template overrides the information about the other VNF(s) and is the only one being really inventoried.

Example: vFW-vPacketGen use case has two VNFs, the vFW and the vPacketGen

Case 1) the CSAR package lists the vPacketGen first and then the vFW. AAI inventory has info about the vFW but not about the vPacketGen.

Case 2) the CSAR package lists the vFW first and then the vPacketGen. AAI inventory has info about the vPacketGen but not about the vFW.

In a nutshell, the last VNF listed in the CSAR wins and makes it to the inventory. The other VNFs don't.
