Currently we don't document how to run Kafka CLI commands in Openshift Container Platform at all. Obviously the expectation is that the user shouldn't need to do this on a day-to-day basis. But, for example, if they're not using the Topic Operator they will need to know how to run `kafka-topics.sh` to list the topics in their cluster. Because of the network policy and the use of the TLS sidecar it's not at all obvious how to execute those commands which take a --zookeeper option.
