Subject: [PATCH] Revert "Require setuptools>=1.0 in all packages that use the
 cryptography lib."

This reverts commit 55b63fca0dad0fae439bb3e453856987e37dea81.
RHEL7 does not come with setuptools >= 1.0, but only 0.9.8.
Since this dependency was only introduced as a workaround for a bug to
enable later versions of cryptography (in particular, cryptography 1.2),
we can safely revert this change until acme/letsencrypt actually uses
newer setuptools features.
