Add the following two options to the ConsumerGroupCommand:

• 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

Proposed Changes

Add JSON/CSV output and looping options to ConsumerGroupCommand. Neither of the these options depend on each other (you can loop in the human readable output, or do a single shot execution with JSON output). Existing behavior/output maintained if neither of the the options are used.

 Adds following two options to ConsumerGroupCommand.

• 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, takes an integer value greater than 0, runs the command that many times at an interval specified by the loop option
