This adds the oauth2 provider `oidc`. It needs an additional argument, the OIDC discovery endpoint to figure out where the auth and token URLs are. Configuration is similar to setting up the Google Authentication with these changes: * `OAUTH2_PROVIDER = oidc` * `OAUTH2_OIDC_DISCOVERY_ENDPOINT = https://auth.exampe.org/discovery`
