Optimize listStatus api in OzoneFileSystem
URL: https://github.com/apache/hadoop/pull/782
Currently in listStatus we make multiple getFileStatus calls. This can be
optimized by converting to a single rpc call for listStatus.
Also currently listStatus has to traverse a directory recursively in order
to list its immediate children. This happens because in OzoneManager all the
metadata is stored in rocksdb sorted on keynames. The Jira also aims to fix
this by using seek api provided by rocksdb.
