SSO Autologin/Autoredirect

[akhil1508]

• If a config option like "autoredirect" is set to true for a given SSO provider, the login page should automatically perform SSO login using this provider
• It can override all other providers if set (should be documented)
• Feature brings better UX

Should I open this in https://github.com/cryptpad/cryptpad instead?

As the code for SSO login is in https://github.com/cryptpad/cryptpad/blob/15c81aa8ccb737a9a1167481f4a699af331364bb/www/login/main.js#L38

[promasu]

This should be fixed by cryptpad/cryptpad#1868 right?
