Description

It has been deprecated since 0.11.0, it was never meant as a publicly
supported API and people should use
`org.apache.kafka.clients.admin.AdminClient` instead. Its presence
causes confusion and people still use them accidentally at times.

`BrokerApiVersionsCommand` uses one method that is not available
in `org.apache.kafka.clients.admin.AdminClient`, we inline it for now.
