Only checking the kubernetes api on the first master when upgrading is not enough.
Each master needs to be checked before it's upgrade.

* copying ssh key no longer required, works with password auth
* use copy module instead of synchronize (which requires sshpass)
* less tasks and always changed tasks
If crictl (and docker) binaries are deployed to the directories
that are not in standard PATH (e.g. /usr/local/bin), it is required
to specify full path to the binaries.
* create a wrapper script with pki options
* supports all kubespray managed container engines

Command line flags aren't added to kube-proxy which results in missing
feature gates set in this component. Add appropriate setting to
ConfigMap instead.

* Added option to force apiserver and respective client certificate to be regenerated without necessarily needing to bump the K8S cluster version
* Removed extra blank line
* Use proper openssl command to differentiate between host and ip in current certificate check
* fixup! Use proper openssl command to differentiate between host and ip in current certificate check
* etcd: etcd-events doesn't depend on etcd_cluster_setup

* etcd: use *access_addresses, do not delegate to etcd[0]
We want to wait for the full cluster to be healthy,
so use all the cluster addresses
Also we should be able to run the playbook when etcd[0] is down
(not tested), so do not delegate to etcd[0]

* etcd: use failed_when for health check
unhealthy cluster is expected on first run, so use failed_when
instead of ignore_errors to remove scary red messages
Also use run_once

- This solves issue #5721 & #5713 (dupes)
- Provide a cleaner default usage pattern for the download role
around etcd that supports 'host' and 'docker' properly
- Extract the 'etcdctl' as a separate task install piece and reuse it where
appropriate
- Update the kubeadm-etcd task to reflect the above change
* Run 'container-engine' after drain.
Move possibly disruptive role 'container-engine' to run after the node
is drained.
As that role have to be run on non-cluster nodes as well (etcd and
calico-rr), and those nodes are not drained, add play for that case.
* Check if api is up before upgrade.
If container engine is restarted in previous role, api controller can
take some time to start. This check ensures api is up before upgrade.
