----------------------------------------

[~hachikuji] I'd like to work on this. Is it possible to push [KIP-175|https://cwiki.apache.org/confluence/display/KAFKA/KIP-175%3A+Additional+%27--describe%27+views+for+ConsumerGroupCommand] forward to avoid conflict between that and the KIP for this JIRA? Thanks.

> It's useful to have a way to delete the offsets of a consumer group explicitly. The reset tool already supports a number of different ways to alter stored offsets, so perhaps we could add a {{--clear}} option. Note that this would require a change to the OffsetCommit protocol which does not currently support deletion. Perhaps if you commit an offset with a retention time of 0, we can treat it as a deletion.
