In perflab-titan-1 account the operator nodepool has 0% disruption budget. This essentially means it will never scale down. So changed this to allow replicas to scale down by matching it what some other nodepools have.

Description / Motivation: The kustomize-controller is failing with
```
kubectl logs kustomize-controller-8589b7fd57-62kv4 -n flux-system | grep error
