[FEATURE] Indie Web Oauth Discovery Protocol

**Name of app / service**
Indie Web Oauth Discovery Protocol (a protocol not an app)
**Link to developer documentation**
https://indieweb.org/obtaining-an-access-token

**Is lack of support preventing you from building workflows, or do you have a workaround?**
Yes, probably need at least a generic way to access any oauth app

**Are there specific actions, or triggers, you'd like to see for this app? Please let us know here or use the Action and Trigger issue templates to open requests for each!**
The micropub protocol would be cool!
