    [OVN] Override notify_nova config in neutron-ovn-db-sync-util

    If either ``notify_nova_on_port_status_changes`` or
    ``notify_nova_on_port_data_changes`` is set in the neutron
    configuration provided to the ``neutron-ovn-db-sync-util`` tool it
    will stop with a Traceback.

    We are already overriding other parts of the ML2 Notification code
    as we do not want it executing while syncing, so let's override
    these configuration options if set as well.
