Add Kafka Schema Registry PORT on the connInfoSecretTarget

[jonatasbaldin]

When enabled, the Kafka Schema Registry uses the same authentication parameters as the Kafka Broker, the only change is the port (today, is 13044).

When generating the connInfoSecretTarget for Kafka, could we verify if the kafkaUserConfig.schema_registry is enabled, and, if so, add a new key to the generated secret named SCHEMA_REGISTRY_PORT with its value?
