### Description of PR
Now when Observer NN is used, if the stateid is delayed , the rpcServer
will be requeued into callqueue. If EditLogTailer is broken or something else
wrong , the call will be requeued again and again.
So Observer should throw ObserverRetryOnActiveException if stateid is
always delayed with Active Namenode for a configured time.
