Refetch method for getting a fresh model instance

It is often useful to get a fresh instance of a model object, with data from db. A typical case is testing some view code using the test client, when the
view is supposed to save some model changes into database. For example:'some_url', {'id':, 'description': 'new'})
fresh_obj = ObjClass.objects.get(
self.assertEqual('new', fresh_obj.description)

This ticket proposes adding a method to Model that can be used to fetch a "fresh" version of a model object from the database. It is functionally the same as the use of objects.get in the example above, but more convenient and elegant.

fresh_obj = obj.refetch()
