When running cluster.yml for new machines what containerd is already
install but Kubernetes cluster were not installed before, the task
"remove-node | List nodes" is failed like

  "changed": false,
  "cmd": [
    "/usr/local/bin/kubectl", "--kubeconfig",
    "/etc/kubernetes/admin.conf", "get", "nodes", "-o",
    "go-template={{ range .items }}{{ .metadata.name }}
    {{ "\n" }}{{ end }}"
   ],
   ..
   "stderr": "error: stat /etc/kubernetes/admin.conf: no such file or directory",

That was due to lack to check the existing Kubernetes cluster exists
or not before running "kubectl drain" command.
This adds the check to avoid the issue.

* Updated openstack cloud controller version to match kubernetes version

* Rolled back file structure change

* [calico] make vxlan encapsulation the default

* don't enable ipip encapsulation by default
* set calico_network_backend by default to vxlan
* update sample inventory and documentation

* [CI] pin default calico parameters for upgrade tests to ensure proper upgrade

* [CI] improve netchecker connectivity testing

* [CI] show logs for tests

* [calico] tweak task name

* [CI] Don't run the provisioner from vagrant since we run it in testcases_run.sh

* [CI] move kube-router tests to vagrant to avoid network connectivity issues during netchecker check

* service proxy mode still fails connectivity tests so keeping it manual mode

* [kube-router] account for containerd use-case

* Sketch of helm-apps role interface

* helm-apps: Early implementation and settings

* helm-apps: Fix README.md example playbook

* fixup! Sketch of helm-apps role interface

* Make the argument specs more explicit

* Remove exposed options from hardcoded default

* Simplify example playbook in README.md

- Define directly the roles parameters
- Add an example of option override for one chart only

* Use release instead of charts

Make explicit that the role is mananing releases, not charts.
Simplify parameters naming

Entering any value causes the play to proceed, e.g., entering "no<Enter>". (This is simply how Ansible's pause module behaves.)

* Update ansible-lint to 5.4.0 (#8607)

It seems that the Rich version 11.0.0 has a breaking change.
So need to update ansible-lint to 5.3.2 or later.

* Fix for ansible-lint no-changed-when rule (#8607)

* There is an issue with etcd v3.5.0 where it resurrects ancient members see: https://github.com/etcd-io/etcd/issues/13196
This issue is clearly fixed in etcd v3.5.2

* Just keep the checksums

* [containerd] add hashes for 1.6.1

* [contained] make 1.6.1 the default

* [containerd] add hashes for 1.5.10

* [containerd] add hashes for 1.4.13

* [nerdct] bump to 0.17.1

Also, do not create unneeded resources (target pools are charged and should
only be created when needed).

[containerd] Upgrade containerd to 1.6.0 and re-enable arm64 architecture with default options (#8555)

* [containerd] add checksums for 1.6.0

* [containerd] promote 1.6.0 as the new default

* [runc] promote 1.1.0 as the new default to allow arm deployments out of the box

* [nerdctl] bump to 0.17.0 to align with containerd 1.6.0

* [reset] allow crictl stopp and rmp commands to fail

This reverts commit 41718024.

this is not complete -- there are almost certainly more instances of
this issue

As far as I can tell this is simply a typo that has existed from the beginning. Having it this way around (`etcd` group as a child and thus subset of `k8s_cluster`) mirrors what is written in the preceeding sentence.
