Review Comment:
Among other things, the background thread uses background events to signal
the application thread to execute the `ConsumerRebalanceListener` callbacks.
It was my understanding from looking at the code for the existing
`ClassicKafkaConsumer` and from previous discussions on this topic that we need
to execute the `ConsumerRebalanceListener.onPartitionsRevoked()` method when
unsubscribing/leaving a group.
