Description

When describing topic or broker configs with the AdminClient, we can request the documentation of configuration settings to be included.

This does not work with topic configs. The issue lies in this line:
https://github.com/apache/kafka/blob/trunk/core/src/main/scala/kafka/server/AdminManager.scala#L767

This uses a KafkaConfig object to look up topic configs. Hence for configurations that have different names between KafkaConfig and LogConfig, no documentation is found!
