title: Apache camel kafka component fail to serialize header after update from 2.21.1 to 2.21.2
body: <p>After I update the apache camel from version 2.21.1 to 2.21.2 I am getting the follow error:</p>
  
  <p><strong>due Magic v1 does not support record headers</strong></p>
  
  <p>I see at <a href="https://github.com/apache/camel/blob/master/components/camel-kafka/src/main/docs/kafka-component.adoc" rel="nofollow noreferrer">https://github.com/apache/camel/blob/master/components/camel-kafka/src/main/docs/kafka-component.adoc</a> that in version 2.22 all headers are serialized to the topic, I don't know why.
  I set up severals headers on the router, And I dont know it serialize to topic and as mainly as byte.</p>
  
  <p>What I need to do? Apply headerFilterStrategy?</p>
