Feature: 392 - Add Percentage Discount

See Issue #392

Description

In order to be able to implement custom voucher types, the voucher type selection will no longer contain a string, but the class that implements that voucher. This requires some changes to the \Extcode\Cart\Domain\Model\Cart\CouponInterface, which are not finalized at this point.

What is certain is that there will be a defined constructor method. Also the method getTax() will be dropped and instead there will be a method getTaxes() which has to return an array instead of a float value. For custom coupons implementing the \Extcode\Cart\Domain\Model\Cart\CartCouponInterface or overriding the existing implementation, adaptations have to be planned with the upgrade to version v9 for TYPO3 v12 and v11.

Furthermore there will be an upgrade wizard, which replaces the existing string “cartcoupon” in the coupon_type against the class \Extcode\Cart\Domain\Model\Cart\CouponFix.
