Apicurio Registry support

Is your proposal related to a problem?

Kafka UI supports the Confluent schema registry. Alternative to it is the Apicurio registry and it supports multiple versions of APIs including the Confluent compatible schema registry - Version 6.

We can use the compatible API (KAFKA_CLUSTERS_0_SCHEMAREGISTRY: http://registry:8080/apis/ccompat/v6) but it requires different API client and converters.

It'll be good if Kafka UI supports the main API of Apicurio - Version 2. For example, Apache Camel supports a wide range of connectors and, when I checked a couple of them, I see they include the Apicurio related JARs. If it is supported, it'll be quite easy to create connectors with it and monitor/manage on the UI.

Describe the solution you'd like

Add another configuration that supports the Apicurio version 2 API.
