> When partitions are being revoked (client received revocation on heartbeat 
> and is in the process of invoking the callback), we need to make sure we do 
> not fetch from those partitions anymore:
>  * no new fetches should be sent out for the partitions being revoked
>  * no fetch responses should be handled for those partitions (case where a 
> fetch was already in-flight when the partition revocation started.
> This does not seem to be handled in the current KafkaConsumer and the old 
> consumer protocol (only for the EAGER protocol). 
> Consider re-using the existing pendingRevocation logic that already exist in 
> the subscriptionState & used from the fetcher to determine if a partition is 
> fetchable.
