Oauthlib vs Authlib
Which library should be used to replace the currently used and deprecated oauth2client. The two main contenders are Oauthlib and Authlib.
Authlib is the more popular of the two choices as seen in this `graph https://python.libhunt.com/compare-authlib-vs-oauthlib`_. For flask the oauthlib developers themselves recommend using authilib https://github.com/lepture/flask-oauthlib#readme
Authlib seems to be the best candidate for this initiative. There is knowledge in the team of the library as it was used in bodhi. It also appears to have an easier to implement and has a flask integration and is recommended for use by the developer.
