So currently, master requirements changes trigger the following jobs:

gate-tempest-dsvm-full
gate-tempest-dsvm-postgres-full
gate-tempest-dsvm-neutron-full
gate-grenade-dsvm
gate-tempest-dsvm-large-ops
gate-tempest-dsvm-neutron-large-ops

If I understood the cross-check idea right, the idea would be to also
run stable/liberty equivalent of those jobs:

gate-tempest-dsvm-full-liberty
gate-tempest-dsvm-postgres-full-liberty
gate-tempest-dsvm-neutron-full-liberty
gate-grenade-dsvm-liberty
gate-tempest-dsvm-large-ops-liberty
gate-tempest-dsvm-neutron-large-ops-liberty

The goal being to protect stable branches from breakage due to
requirements update while they still use the master branch of
openstack/requirements.

If some of those are problematic I guess we could settle for less jobs.
