Add payments with stripe

[rbento1096]

As an admin I want to be able to setup paymetns with stripe.

Each spot will have a specific payment link (given to us by the OC)

• [x] make spot types editable
• [x] add stripe link as an optional field to spot types
• [x] if spot has a link, add a button to open a modal
• [x] modal shows required info and send user to stripe

Can we close this @rbento1096 ?
