   If use MQTT protocol, multiple consumers using the same clientId in the cluster, the last consumer connection should close the previous consumer connection! 
   There are two solutions to this issue:
   
   > 1. Add a new cluster notification when the client’s connections connect to Artemis, close existing connections that use the same clientId when processing cluster-notification. This solution is the best way to address the MQTT agreement.But I don't think it's necessary to solve this problem by sending a cluster-notification every time client connect.
   
   > 2.The solution is this RP used, close existing connections that use the same clientId when processing the CONSUMER_CREATE  cluster-notification. No additional cluster-notification added. Only when a consumer using the same clientId consumes the same topic will it trigger a close connection.
