Always Start pvc-protection-controller and pv-protection-controller **What this PR does / why we need it**: After K8s 1.10 is upgraded to K8s 1.11 finalizer `[kubernetes.io/pvc-protection]` is added to PVCs because `StorageObjectInUseProtection` feature will be GA in K8s 1.11. However, when K8s 1.11 is downgraded to K8s 1.10 and the `StorageObjectInUseProtection` feature is disabled the finalizers remain in the PVCs and as `pvc-protection-controller` is not started in K8s 1.10 finalizers are not removed automatically from deleted PVCs and that's why deleted PVC are not removed from the system but remain in `Terminating` phase. The same applies to `pv-protection-controller` and `[kubernetes.io/pvc-protection]` finalizer in PVs. That's why `pvc-protection-controller` is always started because the `pvc-protection-controller` removes finalizers from PVCs automatically when a PVC is not in active use by a pod. Also the `pv-protection-controller` is always started to remove finalizers from PVs automatically when a PV is not `Bound` to a PVC. **Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*: Fixes N/A This issue https://github.com/kubernetes/kubernetes/issues/60764 is for downgrade from K8s 1.10 to K8s 1.9. This PR fixes the same problem but for downgrade from K8s 1.11 to K8s 1.10. **Special notes for your reviewer**: **Release note**: ```release-note NONE ``` |
