A simple method to copy live Stripe products (and their plans) to your Testing area. The `$illegal_params` array can be modified as needed, and more fields can be added to both creation methods. In my case I just needed the Product Name and Metadata, and have a lot of old plans, so figured I'd get all the data, and remove the illegal or unused p…
