func (h *PodCreateUpdateHandler) Handle(ctx context.Context, req admission.Request) admission.Response

Handle handles admission requests. It will only handle Pod creation and update. It will query the workload that manages it via the pod's ownerReference, and then apply the processing label from the workload onto the pod. In special cases where the pod's ownerReference is a ReplicaSet, it will continue to query its ownerReference to find the corresponding Deployment workload.
