• output.format, if specified, takes "csv" or "json" as value, sets the output format of ConsumerGroupCommand to "csv" or "json"

• loop, if specified, takes an integer value greater than 0, keeps executing the command at an interval of that many seconds until explicitly terminated by the admin/user

• num.iterations, if specified terminates the loop after after that many iterations
