Operate a VNF Instance
    [Documentation]    Test ID: 5.x.y.x
    ...    Test title: Operate a VNF Instance
    ...    Test objective: The objective is to change the operational state of a VNF instance.
    ...    Pre-conditions: VNF instance in INSTANTIATED state (Test ID: 5.a.b.c)
    ...    Reference: section 5.3.3 - SOL003 v2.4.1
    ...    Config ID: Config_prod_VNFM
    ...    Applicability: change the operational state of a VNF instance is supported for the VNF (as capability in the VNFD)
    ...    Post-Conditions: VNF instance still in INSTANTIATED state and the operational state is changed
