Enhancement: Ability to use the "sub" claim from OpenID for the username

[alihacks]

What features would you like to see added?

Currently, the username field is populated from "username", "given_name" or "email" fields - in that order. I would like to populate this from the "sub" claim. I would like to either support that in code or introduce new environment variable OPENID_USERNAME_CLAIM or similar to allow the user to configure this
