Is your feature request related to a problem? Please describe it

KafkaJS is no longer being actively maintained see tulios/kafkajs#1603

Describe the solution you'd like

To use a library with librdkafka bindings instead of the pure javascript implementation provided by kafkajs.

See #12703 (comment)

To use the @confluentinc/kafka-javascript because Confluent Inc. now maintains the underlying librdkafka library. The @confluentinc/kafka-javascript may not be "production ready" but the developers on the project are actively working on getting it production ready.

Teachability, documentation, adoption, migration strategy

This new microservice transport option needs to be documented.

TODO: Expand upon this.

What is the motivation / use case for changing the behavior?

The motivation around this feature is to migrate towards a javascript kafka library that will be maintained in perpetuity.
