* 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.
