Show the member level information. Add CURRENT-EPOCH, TARGETMEMBER-EPOCH , and TARGET- ASSIGNMENT information. The CURRENT-EPOCH means member epoch. Change ASSIGNMENT to CURRENT-ASSIGNMENT. The ASSIGNMENT value format will change from "my_topic:0,my_topic:1,new_topic:0,new_topic:1" to "my_topic:0,1;new_topic:0,1". The original format shows topic name for each partition. The new format only shows topic name one time for all partitions under the same topic.
