KAFKA-5154: Consumer fetches from revoked partitions when SyncGroup fails
with disconnection [WIP]
Scenario is as follows:
1. Consumer subscribes to topic t1 and begins consuming
2. heartbeat fails as the group is rebalancing
3. ConsumerCoordinator.onJoinGroupPrepare is called
3.1 onPartitionsRevoked is called
4. consumer becomes the group leader
5. sends sync group request
6. sync group is cancelled due to disconnection
7. fetch request is sent for partitions that have previously been revoked
