title: how to view kafka headers
body: <p>We are sending message with headers to Kafka using 
  org.apache.kafka.clients.producer.ProducerRecord</p>
  
  <pre><code>public ProducerRecord(String topic, Integer partition, K key, V value, Iterable&lt;Header&gt; headers) {
      this(topic, partition, (Long)null, key, value, headers);
  }
  </code></pre>
  
  <p>How can I actually see these headers using command. kafka-console-consumer.sh only shows me payload and no headers.  </p>
