CreateCustomerCard
 Adds a card on file to an existing customer.  As with charges, calls to `CreateCustomerCard` are idempotent. Multiple calls with the same card nonce return the same card record that was created with the provided nonce during the _first_ call.  Cards on file are automatically updated on a monthly basis to confirm they are still valid and can be charged.
 @param customer_id The ID of the customer to link the card on file to.
 @param body An object containing the fields to POST for the request.  See the corresponding object definition for field details.
 @param [Hash] opts the optional parameters
 @return [CreateCustomerCardResponse]
