> Many use cases involve tranient consumers. These consumers create entries under their consumer group in zk and maintain offsets there as well. There is currently no way to delete these entries. It would be good to have a tool that did something like
>   bin/delete-obsolete-consumer-groups.sh [--topic t1] --since [date] --zookeeper [zk_connect]
> This would scan through consumer group entries and delete any that had no offset update since the given date.
