During investigation, I also noticed that the related
horizon-dsvm-tempest-plugin job is still defined in
openstack/horizon on its stable/queens and stable/rocky branches.

Additionally, the tests/os_horizon-overrides.yml file in
openstack/openstack-ansible-os_horizon contains a lingering
reference to openstack/tempest-horizon according to codesearch.
