Cart total discount achieved general availability status

After collecting feedback during the beta phase, we have moved Cart total price discount target out of beta. The status of the following features has been changed to general availability:

• CartDiscountTotalPriceTarget type on the Cart Discounts API
• DiscountOnTotalPrice and DiscountedTotalPricePortion types on the Carts API
• discountOnTotalPrice field on Cart and Order

This feature lets you build cart discounts targeting the total price of a cart, for example, get 5$ off your cart total. To know more about cart discounts, see Cart Discounts API.
