   RebalanceImpl.rebalanceByTopic();
   consumer的(clientId)消费费多个topic队列时，存在排序靠前的ClientId可能消费队列较多(负载大)，是否Collections.sort()可以采用shuffle()方式，确保可以随机平均；

   AllocateMessageQueueAveragely这个策略？
   按我的理解，queue=5,consumer=2，则consumer1会消费queue0-2(3个queue)，consumer2会消费queue3-4(两个queue)。不能整除的情况下，肯定会有某个consumer要多干点活
