REQUEST_TIMED_OUT for InitProducerIdRequest)

> Key: KAFKA-14417
> URL: https://issues.apache.org/jira/browse/KAFKA-14417
> Project: Kafka
> Issue Type: Task
> Affects Versions: 3.1.0, 3.0.0, 3.2.0, 3.3.0
> Reporter: Justine Olshan
> Assignee: Justine Olshan
> Priority: Blocker

> In TransactionManager we have a handler for InitProducerIdRequests
> [https://github.com/apache/kafka/blob/19286449ee20f85cc81860e13df14467d4ce287c/clients/src/main/java/org/apache/kafka/clients/producer/internals/TransactionManager.java#LL1276C14-L1276C14]
> However, we have the potential to return a REQUEST_TIMED_OUT error in
> RPCProducerIdManager when the BrokerToControllerChannel manager times out:
> [https://github.com/apache/kafka/blob/19286449ee20f85cc81860e13df14467d4ce287c/core/src/main/scala/kafka/coordinator/transaction/ProducerIdManager.scala#L236]
>
> or when the poll returns null:
> [https://github.com/apache/kafka/blob/19286449ee20f85cc81860e13df14467d4ce287c/core/src/main/scala/kafka/coordinator/transaction/ProducerIdManager.scala#L170]
> Since REQUEST_TIMED_OUT is not handled by the producer, we treat it as a
> fatal error and the producer fails. With the default of idempotent producers,
> this can cause more issues.
> Seems like the commit that introduced the changes was this one:
> [https://github.com/apache/kafka/commit/72d108274c98dca44514007254552481c731c958]
> so we are vulnerable when the server code is ibp 3.0 and beyond.
