CyberSource will POST to this view if the user cancels payment. CSRF validation cannot be enabled when this happens.

This commit creates a new page intended only for use when the user cancels payment. The previous implementation relied on the CyberSource callback page, which is not useful for orders placed with the E-Commerce Service.

This functionality is activated by adding a SKU to a non-honor course mode. When the feature is activated, verified orders will be created by the E-Commerce Service instead of LMS. After payment, the E-Commerce Service will also create the enrollment.

If a user is already enrolled in a course, the API is bypassed and a 409 status is returned.

Commerce code has now been updated to exclude CourseMode objects with SKU set to empty string (in addition to null).

Data is now properly encoded as JSON.

This new endpoint is intended to replace enrollment API call used on the login+registration page. Instead of directly enrolling students, the view will contact the external e-commerce API (Oscar) to create a new order. Oscar will be responsible for completing the order and enrolling the student.

This behavior will only apply to course modes with associated SKUs. All other course mode enrollments will be processed directly by LMS.
