Add ability in kafka-pubsub to send trace state to metadata as an option

[passuied]

Describe the feature

PubSub components promote the usage of CloudEvents to include additional information in the message, including tracing information.
However, when working with existing events that do not use Cloud Events, you are losing the ability to having tracing. In some cases, when using Schema Registry, using cloud events is not an option at all... It would be a great option to be able to pass tracing information within the header. Kafka provides headers and currently any metadata added to the pubsub will be passed on as headers in the message.

I suggest providing an option in the Kafka subscription metadata to include tracing info as header automatically.

Release Note

RELEASE NOTE: ADD an option in Kafka PubSub subscription metadata to publish the tracing information as message headers

Based on looking at code it would require to create a span and inject to metadata when publishing a raw payload but that code is in Dapr. Should we move it to Dapr kit instead?
