Kafka node - allow to pass auth options to Registry config

Feature Requests
1

The idea is:

Allow to pass the auth param to Schema Registry in addition of the registry URL when configuring a Kafka node

@kafkajs/confluent-schema-registry has built in support of this basic auth already

My use case:

My Confluent Schema Registry is protected via basic auth and this needs to be configured at node level to be able to produce a message

I think it would be beneficial to add this because:

This is needed when schema registry is behind an auth

Any resources to support this?

Are you willing to work on this?

Yes will open a PR for that
