What this PR does / why we need it

Adds optional pod-level scheduling knobs to the FeatureStore CR so users can place the operator-managed Deployment on specific nodes or on nodes with taints:

spec:
  services:
    nodeSelector:
      kubernetes.io/os: linux
    tolerations:
      - key: dedicated
        operator: Equal
        value: feast
        effect: NoSchedule

Both fields live on spec.services, alongside the existing affinity and topologySpreadConstraints. tolerations is applied directly to the pod spec. nodeSelector becomes the base selector, with the pre-existing per-server containerConfigs.nodeSelector overlaid on top (per-service wins on key conflicts), preserving the existing merge-with-mutating-webhook behavior.

Regenerated artifacts: deepcopy, CRD bases, dist/install.yaml, the API reference, and the OLM bundle.

Please add Tolerations and NodeSelector to api/v1alpha1/featurestore_types.go, regenerate its deepcopy code and both CRD schemas, and add coverage for the served legacy version. v1alpha1 is still served by the CRD, so users submitting that API version currently cannot configure these fields. Similar cross-version CRD changes in this repository update both API packages.

Allow scheduling the operator-managed Deployment on tainted or specific nodes via spec.services.tolerations and spec.services.nodeSelector, alongside the existing affinity and topologySpreadConstraints fields.

@HaoXuAI thanks for the review, I've made the request change, please take another look when available; also failed test seems to be related to GitHub degredation, not the change:
