    Attachment: hdfs-6345-1.patch

Patch attached. I did manual testing with a branch-2 NN and the new client, verified that it still filters correctly, and that we get the same exception thrown on error.

> DFS.listCacheDirectives() should allow filtering based on cache directive ID. Currently it throws an exception.
> For example:
> {code}
> long directiveId = <some id value>;
> CacheDirectiveInfo filter = new CacheDirectiveInfo.Builder()	
>     .setId(directiveId)
>     .build();
> RemoteIterator<CacheDirectiveEntry> itr = dfs.listCacheDirectives(filter);
> {code}
