> * AdminClient should only call Metadata#requestUpdate when needed.
> * AdminClient should retry requests for which the controller has changed.
> * Fix an issue where AdminClient requests might not get a security exception, even when a metadata fetch fails with an authorization exception. 
> * Fix a possible issue where AdminClient might leak a socket after the timeout expires on a hard close, if a very narrow race condition is hit
