/**
 * Adds a free line item as a gift to the cart. The line item will have the {@link LineItemMode#GIFT_LINE_ITEM}.
 * Like all other line items, it has the {@link LineItem#getPrice()} field set (it is therefore necessary that the
 * variant has a price defined that can be selected for each cart the discount should be applied to).
 *
 * The {@link LineItem#getTotalPrice()} has a `centAmount` of `0`.
 * The {@link LineItem#getDiscountedPricePerQuantity()} discounts the full price and links back to this cart discount.
 * If at creation time the discount can not be applied to any cart (e.g. because the product, the variant, or a channel does not exist), the creation fails.
 *
 *  The discount will not be applied to a cart if it either has become invalid since the creation (e.g. because the product, the variant, or a channel have been deleted)
 *  or because no price can be selected for the particular cart.
