1. Changing the DescribeGroups protocol so it also returns the offset information for all topic partitions from which the group has consumed from since its creation. More detailed can be found here.
2. Exposing the added OffsetFetch behavior through a new interface in KafkaConsumer, which would still imply that the dummy consumer has to be created in the group in order to retrieve offsets.  More details can be found here.
3. Passing an empty list, instead of null, to the API to get all offsets. The null value was chosen to remain consistent with how some other APIs handle a similar situation (e.g. TopicMetadata API returns metadata of all topics if it is provided with a null value as list of topics).
