> Ensure that SAML IdPs use https on Chrome OS
> 
> This CL sets a CSP for the GAIA auth extension that ensures the entire
> login flow, including redirects to SAML IdPs, uses https.
> 
> The FakeGaia and FakeSamlIdp classes used in SAML tests use the embedded
> test server, which speaks http only. The CL therefore adds a test server
> written in Python that speaks https and acts as a wrapper by forwarding
> calls to the embedded test server over http.
