can use mqadmin rocksDBConfigToJson command

We need a more elegant approach that can persist consumer offset according to the json consumer offset manage design, rather than using mqadmin to print json 、pip it to a json file 、 rename old
json file and move new json file, I plan to add parameters in mqadmin to control print or persist.
