    KAFKA-3859: Fix describe group command to report valid status when group is 
empty

    With the new consumer, when all consumers of a consumer group are stopped 
(i.e. the group is empty), the describe consumer group command returns 
`Consumer group ... is rebalancing.`
    This PR fixes this issue by distinguishing between when the consumer group 
is actually rebalancing and when it has no active members.
