> Currently in {{FileSystem}}, {{rename}} with _Rename options_ is protected and with _deprecated_ annotation. And the default implementation is not atomic.
> So this method is not able to be used outside. On the other hand, HDFS has a good and atomic implementation. (Also an interesting thing in {{DFSClient}}, the _deprecated_ annotations for these two methods are opposite).
> It makes sense to make public for {{rename}} with _Rename options_, since it's atomic for rename+overwrite, also it saves RPC calls if user desires rename+overwrite.
