[GH-49] Add security object with requestedAuthnContext to include password and x509 to AzureIdPs

If you do not do both of these things, your checks will either not run, or have a high probability of failing.

I like this approach but I haven't had a chance to test this myself, approving all the same as it will be tested eventually, of course.

I haven't seen the change yet on identity-glenrg.iamdev.s.uw.edu, just now:

<samlp:RequestedAuthnContext Comparison="exact">
  <saml:AuthnContextClassRef>urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport</saml:AuthnContextClassRef>
 </samlp:RequestedAuthnContext>

I loaded the code, and the deploy was successful, so it should be there. Hmmm
