    Update messaging notification configuration

    This patch add the conditional inclusion of the notification
    section of the service configuration. This ensures that oslo.messaging
    notifications use the correct transport for deployments that have
    separate rpc and notify messaging backends. For example, if the
    transport_url is not provided in the notification section of the
    service configuration, the transport_url specified in the default
    section will be used instead.

    This patch conditionally selects the notifier driver. The noop
    driver will be selected when notification publishing is disabled.
    The messagingv2 driver is selected when notification publishing is
    enabled.
