Investigate oauth2 support in Trac.

Haiku now has a central identity provider. Investigate attaching Trac to it via oauth2

• https://github.com/SpamExperts/trac-sso -- Read-only abandoned
• https://trac-hacks.org/wiki/OAuth2Plugin -- Last update 2014 😬
• https://github.com/trac-hacks/trac-oidc -- Only works with "google's oidc"

There is also this one which will work with github and is a little newer: https://github.com/trac-hacks/trac-github

I can confirm that trac-oidc works with Google authentication, I use that for my personal Trac instance. How hard would it be to make it work with something else? Isn't oauth2 supposed to be a standard?
