This is a circular import error. If you look at the chain of imports, you'll see that earlier you're in the file "sage/rings/all.py," and the error occurs when you later try to import sage.rings.all.
A brief glance at your code doesn't reveal the cause of the problem for me, though it could be related to creating a new top level folder sage/monoids. I would say that, ideally, the kind of functionality that you're moving from Group to Monoid should go in the categories. Then we don't need an intermediate class in the Python inheritance tree.
