External Line Item Prices

We introduced the new Line Item price mode 'ExternalPrice' in which the prices for line items are set externally while eligible cart discounts will be applied. The external prices can now be set during creation of line items.

• [API] Added the ExternalPrice LineItemPriceMode.
• [API] Added the possibility to set an external total line item price when creating a line item or changing the quantity of a line item with ExternalTotal LineItemPriceMode.
