Retry transactions if 503 error comes back

[alexbain]

Hi, a recent order placed on my woocommerce site failed to complete when the plugin received a 503 error from Coinbase. The order is now stuck in a pending state, and the customer has left the site so we don't have a way to complete the order.

It would be fantastic if the Coinbase plugin, upon receiving a 503, attempted to retry the request a few times (exponential backoff?) before admitting defeat.

Here's the stack trace:

Thanks!

Sorry about the missed sale. We're constantly trying to improve our availability and this should continue to get better as the platform matures.

I don't think retry with exponential backoff makes sense here (since trying again in a few seconds is unlikely to succeed and the user isn't going to sit around much longer waiting for the request to go through).
