Title: Switch cloudformation over to sigv4

I had to update the unittests for cloudformation
to not check the auth params. I ended up just
ripping out the params related to auth, figuring
that my intent with the unittests were to verify that
the passed in user params were being mapped properly
to HTTP params. Auth is really an orthogonal issue, and
deserves its own set of unittests.

This should also make it easier if a new auth version ever
comes out :)

Note that this depends on #859, which includes a small fix
for str()'ing the params in auth.py.
