> When consumer is closed and transaction is not committed or rollbacked, the msg acked is not showed by delivering message but counted by delivering count.
> We add closed consumer if any message is acked but not committed or rollbacked, and remove closed consumer if transaction is finished. In this way, delivering messages can be properly retained.
> During calling hasCosnumer and getConsumerId, there is some race condition that emptyConsumerId is called causing following getConsumerId throws IllegalStateException. Also optimize it without extra effort.
