Manikumar commented on KAFKA-2404:
----------------------------------

looks like this is tricky to implement. We can only remove a config path after 
the empty config list read by all the brokers.
probably we may not require this.  maybe we can close this issue.

[~junrao],  [~rsivaram] Any thoughts?

> "Currently, if I add client config and then remove it, the clientid still 
> shows up during describe, but with empty config values. We probably should

> Configs for client:client1 are"
