Kubernetes 1.19 deprecated APIs

Kubernetes 1.19 deprecated a long list of beta APIs, and all but one of them were removed three releases later, in 1.22. It also brought Ingress to networking.k8s.io/v1, which makes 1.19 the oldest version where every 1.22 replacement is available. ComponentStatus was deprecated here too, with no removal scheduled.
