class_docstr: A class to rename the ``session`` attribute to ``sagemaker_session``.
  
  Rename takes place in ``S3Uploader`` and ``S3Downloader``.
  
  This looks for the following calls:
  
  - ``sagemaker.s3.S3Uploader.<function>``
  - ``s3.S3Uploader.<function>``
  - ``S3Uploader.<function>``
  
  where ``S3Uploader`` is either ``S3Uploader`` or ``S3Downloader``, and where
  ``<function>`` is any of the functions belonging to those two classes.
