Add test for these functionalities for camel-quarkus-kafka extension :

• Capability to use manual commit with Kafka consumer
• Customize Kafka header propagation
• Switch to Strimzi container
• Serialization/Deserialization of keys,headers, etc.
• Open discusion about scenario "Customize Consumer error handling"
  • No test found. Not even in the camel repository. I’m not sure this one is easy to test. Can we skip this test ?
