+If this item has any discounts, returns a hashref in the format used
+by L<FS::Template_Mixin/_items_cust_bill_pkg> to describe the discount(s)
+on an invoice. This will contain the keys 'description', 'amount', 
+'ext_description' (an arrayref of text lines describing the discounts),
+and '_is_discount' (a flag).
+
+The value for 'amount' will be negative, and will be scaled for the package
+quantity.
