* Wait for kube-apiserver availability before starting upgrade
I am experiencing a timing issue when upgrading from kubespray
2.11.0(k8s 1.15.3) to kubespray 2.12.6(k8s 1.16.9). The certificates get
replaced in `kubeadm-secondary-legacy.yml` and kube-apiserver notices a mismatch
(for a fraction of a second) between `apiserver.crt` and `apiserver.key`
which causes it to restart. And sometimes ( ~ 1 out of 5 upgrades) the
kube-apiserver isn't back on time for the start of the upgrade task. It
fails when kubeadm checks with the kube-apiserver to start the upgrade. The
kube-apiserver returns a `connect: connection refused`. I have created this
small task to check the availability of the kube-apiserver before starting the
upgrade, so that the upgrade will run without an issue.

Also we should be able to run the playbook when etcd[0] is down
(not tested), so do not delegate to etcd[0]

unhealthy cluster is expected on first run, so use failed_when

CIDR notation in no_proxy is supported by a lot of programs/languages,
including go: https://github.com/golang/go/issues/16704
Without that containerd cannot talk the the API server (kube_apiserver_ip),
but it should not go through an external proxy for the nodes/pods/services

Initially this was to fix a mis-indented approvers key. However, it turns
out that 'oilbeater' is not a member of kubernetes-sigs nor
kubernetes-incubator (the org this repo was migrated from). Thus this
OWNERS file is failing prow's validation check.
As a workaround I've opted to move them to emeritus_approver, which
isn't valiated and can be used as a hint for other approvers in this
repo
This fixes the scenario where masters are upgraded one at a time
and coredns gets improperly scaled back up to 2 replicas.
