  The mapping of kafka bootstrap server endpoints i.e. 1.2.3.4:9094=0.0.0.0:9092 to assign bootstrap server mapping.
If Kafka is installed on Kubernetes, run `kubectl get svc` and acquire the list of load balanced bootstrap IP.
For example, the output below of `kubectl get svc` would require the 'Configuring as' shown following.

NAME    TYPE          CLUSTER-IP  EXTERNAL-IP   PORTS
kafka-0 LoadBalancer  34.1.2.3    10.1.2.3      tcp-external:9094►12345
kafka-1 LoadBalancer  34.1.2.4    10.1.2.4      tcp-external:9094►12346
kafka-2 LoadBalancer  34.1.2.5    10.1.2.5      tcp-external:9094►12347

Configuring as

  "10.1.2.4:9094": 9093,
  "10.1.2.5:9094": 9094,
}

yields when computing the kafka-proxy flags:
  10.1.2.3:9094=0.0.0.0:9092,
  10.1.2.4:9094=0.0.0.0:9093,
