Documentation     Test of open ONU go adapter PM data
...               in case of kafka pod runs in k8s cluster - kafka has to deploy with following EXTRA_HELM_FLAGS
...               --set externalAccess.enabled=true,
...               --set externalAccess.service.type=NodePort,
...               --set externalAccess.service.nodePorts[0]=${KAFKA_PORT},
...               --set externalAccess.service.domain=${KAFKA_IP}
...               with e.g. service.domain=10.0.02.15 or 127.0.0.1 and service.nodePorts[0]=30201!
...               For voltha-infra prefix kafka. is needed e.g.: --set kafka.externalAccess.enabled=true
