ECOM-2562

There's no need to use a string literal in setattr, delattr, or the
two-argument form of getattr.

Please note that this is a squshed commit and the work of:
Symbolist, macdiesel, nedbat, doctoryes, muzaffaryousaf and muhammad-ammar

Also remove useless docstrings where they were added to keep pylint
quiet.

The previous value means that those dates would have the value of
whenever the models were imported.
