Example: How to I deauthorize a token?

Created by: jeffblake

Many OAuth providers have the ability to disconnect a token. E.g.:

Quickbooks: https://developer.intuit.com/docs/0150_payments/0060_authentication_and_authorization/oauth_management_api

Stripe: https://stripe.com/docs/connect/reference

Is there a roadmap for integrating this into the oauth2 gem?
