    KAFKA-5269: Correct handling of UNKNOWN_TOPIC_OR_PARTITION error 

    We should retry AddPartitionsToTxnRequest and TxnOffsetCommitRequest when receiving an UNKNOWN_TOPIC_OR_PARTITION error.
    
    As described in the JIRA: It turns out that the `UNKNOWN_TOPIC_OR_PARTITION` is returned from the request handler in KafkaAPis for the AddPartitionsToTxn and the TxnOffsetCommitRequest when the broker's metadata doesn't contain one or more partitions in the request. This can happen for instance when the broker is bounced and has not received the cluster metadata yet. 
    
    We should retry in these cases, as this is the model followed by the consumer when committing offsets, and by the producer with a ProduceRequest.
