LGTM, left some comments

This creates a fresh session without the super().get_session() semantics which ensure a retry behavior is configured. I would propose to refactor Credentials.get_session() to call a new method self._create_and_save_session(). This new method can then be re-used in this line to ensure a retry configuration is being set properly.

I propose to include setting self._session in this new method as well (in contrast to a pure self._create_session() method) because the management of this attribute is an internal aspect of the super class.
