        Add a CertificateItem to an order

        Returns the CertificateItem object after saving

        `order` - an order that this item should be added to, generally the cart order
        `course_id` - the course that we would like to purchase as a CertificateItem
        `cost` - the amount the user will be paying for this CertificateItem
        `mode` - the course mode that this certificate is going to be issued for

        This item also creates a new enrollment if none exists for this user and this course.

        Example Usage:
            cart = Order.get_cart_for_user(user)
            CertificateItem.add_to_order(cart, 'edX/Test101/2013_Fall', 30, 'verified')
