RFE-9431: expose full openAPIV3Schema for pruner, scheduler, and networkpolicy configs

[anasalli]

Changes

Removes +kubebuilder:validation:Schemaless from three configuration types so that oc explain shows the full schema for configurable fields in the TektonConfig CRD.

Before: oc explain tektonconfig.spec.tektonpruner.global-config shows just <Object> with no fields.

After: Shows all configurable fields (enforcedConfigLevel, ttlSecondsAfterFinished, historyLimit, namespaces, etc.)

Ref: https://redhat.atlassian.net/browse/RFE-9431

What was changed:

• Removed // +kubebuilder:validation:Schemaless from:
  • SchedulerConfig.Config in tektonscheduler_types.go (exposes: queueName, multiKueueOverride, cel)
  • TektonPrunerConfig.GlobalConfig in tektonpruner_types.go (exposes: ttlSecondsAfterFinished, historyLimit, namespaces, etc.)
  • NetworkPolicyConfig.Policies in networkpolicy_config.go (exposes: podSelector, ingress, egress)
• Kept +kubebuilder:pruning:PreserveUnknownFields on all three fields for backward compatibility
• Regenerated all affected CRDs via controller-gen v0.18.0

Size Impact

CRD	Before	After	Limit
TektonConfig	71 KB	111 KB	256 KB

All CRDs remain well under the 256 KB size constraint enforced by hack/sync-helm-crds.sh.

Why not expand AdditionalOptions?

The AdditionalOptions fields (Deployments, StatefulSets, ConfigMaps, HPAs) embed full Kubernetes types that would each add ~100 KB per instance across 11 components, pushing the CRD far over the 256 KB limit. These remain schemaless by necessity.

Testing

• Applied the regenerated CRD to an OCP 4.21.18 cluster with OpenShift Pipelines 1.23.0
• Verified oc explain now shows full field schemas for all three types
• Verified TektonConfig resource remains Ready=True with all conditions healthy
• No disruption to running Tekton components (18 pods in openshift-pipelines namespace)

Submitter Checklist

• Run make test lint before submitting a PR
• Includes tests (if functionality changed/added)
• Includes docs (if user facing)
• Commit messages follow commit message best practices

See the contribution guide for more details.

Release Notes

Exposed full openAPIV3Schema for TektonConfig CRD fields: tektonpruner global-config, scheduler config.yaml, and networkPolicy policies. Users can now run `oc explain tektonconfig.spec.tektonpruner.global-config` to see all configurable fields instead of just `<Object>`.
