AKS ImageCleaner user raised issue:
If eraser-controller-manager pod is restarted, the ImageJob is cleaned up but the PodTemplate and eraser pods are left behind (since controller-manager-pod is not deleted in this case). In this example, manager pod restarted twice and two PodTemplates are left behind:
kubectl get podtemplate -A
NAMESPACE NAME CONTAINERS IMAGES POD LABELS
kube-system imagejob-dhtbn collector,remover,trivy-scanner mcr.microsoft.com/oss/eraser/collector:v1.2.2,mcr.microsoft.com/oss/eraser/remover:v1.2.2,mcr.microsoft.com/oss/eraser/eraser-trivy-scanner:v1.2.2

What did you expect to happen:
PodTemplates and Pods should be cleaned up if manager restarts, not just when it is deleted.
