Change external connectivity of VNF Workflow
    [Documentation]    Test ID: 7.3.1.20
    ...    Test title: Change external connectivity of VNF Workflow
    ...    Test objective: The objective is to change the external connectivity of a VNF instance.
    ...    Pre-conditions: VNF instance in INSTANTIATED state 
    ...    Reference: Clause 5.4.11 - ETSI GS NFV-SOL 003 [1] v2.6.1
    ...    Config ID: Config_prod_VNFM
    ...    Applicability: NFVO is able to receive notifications from VNFM. The VNFD supports the external connectivity change
    ...    Post-Conditions: VNF instance still in INSTANTIATED state and external connectivity of the VNF is changed
