Obtain information from Kroxylicious Kube CRs when a Kafka cluster connection is configured as a proxy (new configuration properties).

The initial implementation may include:

• An indicator that a Kafka cluster is a proxied cluster (i.e. virtual Kafka cluster)
• Tailored presentation of cluster metrics for direct vs. proxy Kafka connections
• Display of linkage between a virtual Kafka cluster and the real cluster (if configured in the console)
• Display of virtual Kafka cluster configuration; filters, configuration properties, ingress information
