[webpayments] Machine readability of payment methods? (#30)

The [Payment Method Identifiers](http://wicg.github.io/paymentrequest/specs/method-identifiers.html#issue-4) asks:
> If the payment method identifier is a URL, should there be a resource that can be fetched from the URL? Is there a need to describe the payment method at the URL or provide some other information?
