PunchOutOrderRequestParser pipeline

PunchOut is a mechanism by which the e-procurement application makes it possible for a buyer to access a supplier's Web site from the buyer's own procurement application.
Configured Commerce integrates with PunchOut, but may require customization. The following sample code shows how to extend the PunchOutOrderRequestParser to accommodate additional fields.
The following extends the schema by storing the new field's temporary storage using HttpContext as an item collection. Dependency injection will detect the new plugin and use it automatically.
