OAuth 2.0 Device Authorization Grant flow, used by the YouTube TV client (youtube.com/tv).
For more information regarding OAuth 2.0 and the Device Authorization Grant flow in general, see:
- https://developers.google.com/identity/protocols/oauth2/limited-input-device
- https://accounts.google.com/.well-known/openid-configuration
- https://www.rfc-editor.org/rfc/rfc8628
- https://www.rfc-editor.org/rfc/rfc6749
Note: The official client appears to use a proxied version of the oauth2 endpoints on youtube.com/o/oauth2,
which applies some modifications to the response (such as returning errors as 200 OK).
Since the client works with the standard API, we will use that as it is well-documented.
