Review Comment:
Agree, the `clearAll` was only being called from poll, when draining the
requests to send
https://github.com/apache/kafka/blob/bc3a18c59c638f267d9ebe28105be6b94f659f4f/clients/src/main/java/org/apache/kafka/clients/consumer/internals/CommitRequestManager.java#L193
If there was a fatal coordinator error, the poll does an early return so we
would never call `clearAll` and the failed requests would forever remain in the
queue I expect (even after expiration even, because the early return wouldn't
even allow to make it to the `failAndRemoveExpiredCommitRequests`). Makes sense
@kirktrue? (ln 207 doesn't have a clearAll so just want to make sure we're
looking at the same things)
