Create new stripe-payment-method.

Create a new stripe-payment-method for an account.

This is the second setup when adding a credit card to an account. After creating a setup-intent and
confirming it with a payment-method, call this operation to complete the addition of a credit
card to an account.

Note, only one credit card can be active at a time. Anytime a new credit card is added to an account
it becomes the active card.
