    [rabbit] use retry parameters during notification sending

    The rabbit backend now applies the [oslo_messaging_notifications]retry,
    [oslo_messaging_rabbit]rabbit_retry_interval, rabbit_retry_backoff and
    rabbit_interval_max configuration parameters when tries to establish the
    connection to the message bus during notification sending.

    This patch also clarifies the differences between the behavior
    of the kafka and the rabbit drivers in this regard.
