produce the work, or an object code interpreter used to run it.

  The "Corresponding Source" for a work in object code form means all

- `StatefulSet` names must be DNS labels, rather than subdomains. Any `StatefulSet`
  which took advantage of subdomain validation (by having dots in the name) can't
  possibly have worked, because we eventually set `pod.spec.hostname` from the `StatefulSetName`,

- Fix the bug PIP's DNS is deleted if no DNS label service annotation isn't set. ([#87311](https://github.com/kubernetes/kubernetes/pull/87311), [@nilo19](https://github.com/nilo19)) [SIG Cloud Provider]

- Kubeadm: during 'upgrade apply', if the kube-proxy ConfigMap is missing, assume that kube-proxy should not be upgraded. Same applies to a missing kube-dns/coredns ConfigMap for the DNS server addon. Note that this is a temporary workaround until 'upgrade apply' supports phases. Once phases are supported the kube-proxy/dns upgrade should be skipped manually.
