Clark Boylan 05aa3846a0 Just use constraints everywhere
Having behavior on your laptop diverge from behavior in the gate is
confusing. Just use constraints on every devstack run to be consistent.
Users of devstack can edit the requirements repo in order to change
these constraints locally if necessary.
