    rabbit: Don't prefetch when batch_size is set

    When the application set batch_size, so we don't need to prefetch more
    messages, especially for notifications. Notifications queues can be
    really big when the consumer have disapear during a long period, and
    when it come back, kombu/pyamqp will fetch all messages it can. So we
    override the qos prefetch value.
