move from python-cloudfiles to pyrax
feedmagnet/deployment#1449

Pyrax is the new way to connect to the rackspace cloud.  This change
simply uses it at the python bindings for doing that.  Note that
the functionality for setting the expiry on a backup file is currently
non-functional since Pyrax does not yet support the header
x-delete-after.
