This implements functionality to automate restarting a login.
The automation of CSRF errors catches missing CSRF cookies to retry as fallback for Logins that required too much time.
The IdP errors are implemented because some IdP Providers return with errors where it is advised to directly retry the login process. For example keycloak handles its "temporarily_unavailable" error like this. See https://www.keycloak.org/securing-apps/oidc-layers#_oidc-errors
