OCPNODE-4730: Add Workload API feature gates for TechPreviewNoUpgrade

[sairameshv]

Adds the Kubernetes Workload API (workload aware scheduling) feature gates, enabled in the TechPreviewNoUpgrade and DevPreviewNoUpgrade feature sets:

• GenericWorkload: the Workload/PodGroup APIs and pod.spec.schedulingGroup
• GangScheduling: all-or-nothing scheduling of a pod group
• WorkloadWithJob: Job controller creation of Workload/PodGroup objects
• WorkloadAwarePreemption: workload aware preemption and its API fields
• TopologyAwareWorkloadScheduling: topology aware placement of pod groups
• DRAWorkloadResourceClaims: ResourceClaims shared across a PodGroup

The gate names match the upstream Kubernetes feature gates so that they can be passed through to the kube components as-is.

Pipeline controller notification
This repo is configured to use the pipeline controller. Second-stage tests will be triggered either automatically or after lgtm label is added, depending on the repository configuration. The pipeline controller will automatically detect which contexts are required and will utilize /test Prow commands to trigger the second stage.

For optional jobs, comment /test ? to see a list of all defined jobs. To trigger manually all jobs from second stage use /pipeline required command.

📝 Walkthrough

Walkthrough

The change registers six node feature gates: GenericWorkload, GangScheduling, WorkloadWithJob, WorkloadAwarePreemption, TopologyAwareWorkloadScheduling, and DRAWorkloadResourceClaims. It documents their preview availability and updates 4.10 Hypershift and SelfManagedHA manifests. Default and OKD profiles disable the gates. DevPreviewNoUpgrade and TechPreviewNoUpgrade profiles enable them, except DRAWorkloadResourceClaims remains disabled in the SelfManagedHA TechPreview profile.

Suggested reviewers: vr4manta

Priority: ⬇️ Low

Merge Risk: 🟡 Moderate · up to bc686

One feature-gate manifest (SelfManagedHA TechPreviewNoUpgrade) incorrectly enables the DRAWorkloadResourceClaims gate when it should remain disabled for that profile per the PR's own design, meaning clusters on that profile could get an unsupported, immature capability turned on. The fix is a small, well-understood edit (moving one entry between two lists), but it should be corrected before merge to avoid shipping an unintended feature-gate default.
