Spike: Enable Pre-auth payment method

[bborman22]

The goal of this spike is to get a sense of scope and touch points needed to enable the Pre-authorized debit payments in Canada. This task should be timeboxed to about 2 to 3 days and conclude with a write up on the findings. The write up should allow us to give a more accurate estimate for effort to enable pre-auth. Some of the questions we should look to answer (include, but not limited to):

• What efforts are required through the Stripe account, if any, to enable for set up, testing, communication.
• How much / is there any underlying code we can re-use between payment methods including pre-auth?
• What areas of the codebase would need to be touched? Is it just a matter of adding a relevant payment method class?
• Ensuring the new checkout experience is supported.
• Exploring support in all checkout experiences.
• Checking for what is required to check payment status.
• A nice to have would be a proof of concept branch to explore.
