This implements both a SAML2 metadata endpoint (at `/_matrix/saml2/metadata.xml`), and a SAML2 response receiver (at `/_matrix/saml2/authn_response`). If the SAML2 response matches what's been configured, we complete the SSO login flow by redirecting to the client url (aka `RelayState` in SAML2 jargon) with a login token. What we don't yet have is anything to build a SAML2 request and redirect the user to the identity provider. That is left as an exercise for the reader.
