[Openstack-stable-maint] py34 on stable/* ?

Hi Jeremy, I assume adding py34 env on stable branches was a mistake or is there more to this than what's in the commit message? https://review.openstack.org/#/q/branch:stable/havana+topic:py34,n,z https://review.openstack.org/#/q/branch:stable/icehouse+topic:py34,n,z Cheers, Alan
