> According to docs [0] `Consumer#unsubscribe` should clean both subscribed and
> assigned partitions. However, there are two issues about `AsyncConsumer`
> 1) if we don't set group id, `AsyncConsumer#unsubscribe`[1] will be no-op
> 2) if we set group id, `AsyncConsumer` is always in `UNSUBSCRIBED` state and
> so `MembershipManagerImpl#leaveGroup`[2] will be no-op
