The requirements project is very slow to actually tag branches as EOLd as that can cause some testing environments and devstack to fail. For example if tox.ini refers to a constraints file in git[1]. However building wheels for those releases isn't actually helpful as they're not chnaging *and* can cause failed runs as pypi etc move on. This change adds an regex for the closed branches to exclude them from building. The regex is a little more complex than the single case (newton) requires but allows for easier future additions.
