Note :
1. Get grant from NFVO ( if needed ) .
Request grant information is made from ExtVirtualLinkData
of ChangeExtConnRequest . If ExtVirtualLinkInfo is changed
from instantiated VNF , we inform VnfLinkPortInfo related

related to each individual VnfExtCpInfo .
2. Call vnflcm_driver to change networks .
Invoke vnflcm_driver to perform change external VNF
connectivity .
3. Update VNF information
Update InstantiatedVnfInfo as a post - processing .
