Description

The controller currently implements Metadata incompletely. Specifically, it does not return the metadata for any topics in the cluster. This may tend to cause confusion to users. For example, if someone used the controller endpoint by mistake in `kafka-topics.sh --list`, then they would see no topics in the cluster, which would be surprising. It would be better for 3.0 to disable Metadata on the controller since we currently expect clients to connect through brokers anyway.
