ECOM-2972

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

MAYN-65 fixed the bug, removed the redemption table entry when the item is expired from the user cart

fix quality issues

Block users from enrolling in a course if the user
is blocked by country access rules.

1) Enrollment via the login/registration page.
2) Enrollment from the marketing iframe (via student.views.change_enrollment)
3) Enrollment using 100% redeem codes.
4) Enrollment via upgrade.

This does NOT cover enrollment through third party authentication,
which is sufficiently complex to deserve its own commit.

Show ordinary receipt unless the student is in the payment flow.

Conflicts:
	lms/djangoapps/shoppingcart/views.py

These were found by the new pylint checker I wrote! :)

Removes old payment and verification endpoints, views, templates, and tests, making the new split flow the default. The SEPARATE_VERIFICATION_FROM_PAYMENT feature flag is also removed.

When changing quantities, be sure to return the new CyberSource submit form html. Also, to ensure that any browser content is fully refreshed when clicking the back button, force a page refresh to reset client state
