Policy Change Notification
    [Documentation]    Test ID: 10.3.1.8.1
    ...    Test title: Policy Change Notification
    ...    Test objective: The objective is to test the dispatch of Policy Change Notification when the policy is changed, and perform a JSON schema and content validation of the delivered notification. The action that triggers the notification under test is an explicit test step, but it is not performed by the test system.
    ...    Pre-conditions: A subscription for policy change notification is available in the NFV-MANO.
    ...    Reference: Clause 5.5.9.3.1 - ETSI GS NFV-SOL 012 [7] v3.4.1
    ...    Config ID: Config_prod_NFV-MANO
    ...    Applicability: none
    ...    Post-Conditions: none
