The removed attributes were needed in order to inform the move of the `_verify_user` function call up out of the try/except block. That work has concluded (https://github.com/edx/edx-platform/pull/29324) so the monitoring can be removed. Also: - Bring a comment on some other monitoring up to date - Make long-needed corrections to an existing docstring - Remove malformed-cookie logging, since we haven't been using it
