> When application use consume client in Broadcast model which runs in the 
> docker,we can pull message only from fist offset, because docker allocate the 
> apps at random and cause the store file do not reuse. However, we only want 
> to pull message from last offset sometimes even though the apps runs in the 
> docker, and we can use MQBroadcastFromLastConsumer in this case.
