Bug description:
  When using redis as zmq backend,the keys in redis maybe like follows:

   "service"
   "service.host1"
   "service.host1.host1"
   "service.host2"
   "service.host2.host2"
   "service.host3"
   "service.host3.host3"

  If we stopped the service on host1, the key named
  service.host1 and service.host1.host1 shoule be delete.
  As the result, the topicexchange message would not sent to host1.
  But the fact is service.host1 still exsit, and topicexchange message may still sent to host1.
