Move large-ops test to check pipeline

large-ops has been running for a week in silent mode with great results,
lets move it over to the check pipeline as non-voting as the second step
in making this check gating.

Put gate-tempest-devstack-vm-large-ops test ever where that
gate-tempest-devstack-vm-full is running.
