Will be called to cancel a payment. The default implementation fails if the payment is
``OrderPayment.PAYMENT_STATE_PENDING`` and ``abort_pending_allowed`` is false. Otherwise, it just sets the
payment state to canceled. In some cases you might want to modify this behaviour to notify the external provider
of the cancellation.
On success, you should set ``payment.state = OrderPayment.PAYMENT_STATE_CANCELED`` (or call the super method).
On failure, you should raise a PaymentException.
