Removed apis still exits in latest code

Created by: zryfish

Per https://kubernetes.io/blog/2021/07/14/upcoming-changes-in-kubernetes-1-22/, there are lots of apis will be removed, include

admissionregistration.k8s.io/v1beta1
apiextensions.k8s.io/v1beta1
apiregistration.k8s.io/v1beta1
authentication.k8s.io/v1beta1
authorization.k8s.io/v1beta1
certificates.k8s.io/v1beta1
coordination.k8s.io/v1beta1
extensions/v1beta1
networking.k8s.io/v1beta1

Which I still found in our code base.
