Comment 6 for bug 1704148

To avoid similar wedges, changes to the openstack/tempest repository's master branch (the only branch it has) are tested against supported stable branch versions of some tempest jobs like gate-tempest-dsvm-neutron-full-ubuntu-xenial-ocata and gate-tempest-dsvm-neutron-full-ubuntu-xenial-newton. You might consider creating branch-overridden versions of gate-keystone-dsvm-functional-ubuntu-xenial along those lines.
