Close delegate producer after OutOfOrderSequenceException and UnknownProducerIdException

/**
 * This exception is raised by the broker if it could not locate the producer metadata associated with the producerId
 * in question. This could happen if, for instance, the producer's records were deleted because their retention time
 * had elapsed. Once the last records of the producerId are removed, the producer's metadata is removed from the broker,
 * and future appends by the producer will return this exception.

public class UnknownProducerIdException extends OutOfOrderSequenceException {

/**
 * This exception indicates that the broker received an unexpected sequence number from the producer,
 * which means that data may have been lost. If the producer is configured for idempotence only (i.e.
 * if <code>enable.idempotence</code> is set and no <code>transactional.id</code> is configured), it
 * is possible to continue sending with the same producer instance, but doing so risks reordering
 * of sent records. For transactional producers, this is a fatal error and you should close the
 * producer.

This is fixed in the 2.4 broker, but we should add the code anyway in case older brokers are in use.
