Review Comment:
I was expecting to see here the logic for wrapping the callback error into a
`KafkaException`, but I see it is at a lower level in the
`invokeRebalanceCallbacks`, which it's a bit more obfuscated I would say? Still
I see how it's deeply tied to the
`ConsumerRebalanceListenerCallbackCompletedEvent` so ok for me to leave as it
is if we feel it's clear enough.
