Operate a VNF Instance
    [Documentation]    Test ID: 7.3.1.28
    ...    Test title: Operate a VNF Instance
    ...    Test objective: The objective is to test the workflow of operational change of a VNF instance.
    ...    Pre-conditions: VNF instance in INSTANTIATED state 
    ...    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
    Send Change VNF Operational State Request
    Check HTTP Response Status Code Is    202
    Check HTTP Response Header Contains    Location 
    Check Operation Occurrence Id existence
    Check Operation Notification For Operate    STARTING
    Check Operation Notification For Operate    PROCESSING
    Check Operation Notification For Operate    COMPLETED
    Check Postcondition VNF OPERATE
