kafka record headers are not being handled

[nareshv]

Is your enhancement request related to a problem? Please describe.
Using this as a drop-in replacement for the KafkaProducer & KafkaConsumer coming from native kafka libraries. When the ProducerRecord is having any Header entries, they are not being sent to message, causing the consumer not able to access these headers

Describe the solution you'd like
Ideally, all the kafka record headers should be passed as-is so that the consumer can access them via KafkaConsumer interface.

Describe alternatives you've considered
None

Additional context
None
