As of API version 2020-07, we're updating the allocation method for discounts that have set the
explicit. Currently, Shopify applies these discounts to a single line item, which corresponds to an allocation method of
one. With this change, the allocation methods will instead include "each" and "across".
We're making this change to add "each" functionality, and simplify the discount syntax, as "one" and "across" functionally both discount the final price by a set amount.
