Renames this file system entity.
Returns a Future<FileSystemEntity> that completes with a FileSystemEntity instance for the renamed file system entity.
If newPath identifies an existing entity of the same type, that entity is replaced. If newPath identifies an existing entity of a different type, the operation fails and the future completes with an exception.
Future<FileSystemEntity> rename(String newPath);
