During a split update, the continuous control plane check runs in the background creating and deleting VMs in a loop. When tobiko tests run in the intermediate post-services test stage, they may encounter these transient VMs in BUILD state, causing non-deterministic failures (HTTP 409 Conflict / HTTP 404). Override cifmw_test_operator_stages in the post-services test task to run only tempest, excluding tobiko from the intermediate stage. Tobiko continues to run in the final post-update test stage (in update-edpm.yml), after the control plane check has been stopped.

Summary
During a split update (
cifmw_update_variant: split), the "Run tests after Services update" task inupdate_variant_split.ymlruns the fullcifmw_test_operator_stages(tobiko + tempest) while the continuous controlplane check is still active in the background.
The control plane check continuously creates and deletes VMs, which can collide with tobiko's
action_on_all_instances('active')call, causing non-deterministic failures when tobiko encounters VMs inBUILDstate.This PR overrides
cifmw_test_operator_stagesin the intermediate post-services test task to only include tempest. Tobiko continues to run as before in the final post-update stage (update-edpm.yml), where the control plane check has already been stopped.Context
This is an alternative approach to #3978, which stops and restarts the control plane check around the intermediate tests. This approach was suggested during review as a cleaner solution that preserves uninterrupted control plane monitoring throughout the entire update.
