[Satosa-dev] forced reauthentication at the authenticating IdP?

We have added support for setting "force authn" when the SAMLFrontend receives an authentication request with with that bit on. This is part of this PR: https://github.com/IdentityPython/SATOSA/pull/182 which introduces four new configuration options: * CONTEXT_STATE_DELETE * remember_selected_idp_from_disco * use_disco_when_forceauthn * mirror_saml_forceauthn We have been using this in production for more than 1 year.
