Draft: Update parameters for Zuora iframe
What does this MR do and why?
This MR updates the Zuora iframe parameters to test a new method of payment in Zuora i.e. Credit Balances as one time payment flow of Zuora. This is done because some types of 3DS authentication required cards are not able to collect payment through the Zuora orders API which we currently used in production. More details can be found in this discussion.
