Docker: replace the use of containerd_version with docker_containerd_version to avoid causing conflicts when bumping containerd_version (#8130)

krew release urls changed since v0.4.2, clearly OS type and arch inside the filename.

from:
  https://github.com/kubernetes-sigs/krew/releases/download/v0.4.1/krew.tar.gz
to:
  https://github.com/kubernetes-sigs/krew/releases/download/v0.4.2/krew-linux_amd64.tar.gz

define `host_os` like `host_architecture` determine which OS is krew
installed at.

* Limit kubectl delete node to k8s nodes

This avoids the use of `kubectl delete node` when removing etcd nodes
which are not part of the cluser (separate etcd)

* Take errors into account when deleting node

There should not be error now that we're limiting the deletion to nodes
actually in the cluster

* Retrying on error

This fixes the preinstall check for cloud_provider option based on
inventory/sample/group_vars/all/all.yml

* Added ArgoCD kubernetes-app

* Update argocd_version to latest

* cert-manager: add trusted internal ca when configured

* wrong check for inventory variable

* Update documentation

* Fix containerd install for fcos

Fix-CI: python was upgraded in CI to 3.10 and pathlib is now included in python base making this dependency break the CI (#8153)

I guess `kubernetes-the-hard-way` should be `kubernetes-the-kubespray-way` because of recently created network name is `kubernetes-the-kubespray-way`.

* Ensure addon-resizer 1.8.11 only effective at arch amd64.

k8s.gcr.io/addon-resizer:1.8.11 returns the amd64 image which is not executable at arm64.

Disable addon-resizer when the platform is not amd64.

When metrics-server upgrade and use addon-resizer:2.3, then revert this
commit and `image_arch` will determine the `addon_resizer_image_tag`.

* Add metrics_server_resizer architectures check

* add weave_npc_extra_args in template

* add defaults weave_npc_extra_args

* add sample for weave_npc_extra_args

restarting network in ubuntu 21.04 fails and checked the restart menu and found that hirsute was missing in the argument : )

* fix(metrics-server): update defaults

* fix(metrics-server): typo error

* nginx-ingress: bump to 1.0.4

* Disable builtin ssl_session_cache solving the problem with OpenSSL consuming memory.
* Print warning only instead of error if no IngressClass permission is available.

* nginx-ingress: bump to 1.0.4 in the README

* Disable builtin ssl_session_cache solving the problem with OpenSSL consuming memory.
* Print warning only instead of error if no IngressClass permission is available.

kube-bench scan outputs warning related to Calico like:

* text: "Ensure that the Container Network Interface file
  permissions are set to 644 or more restrictive (Manual)"
* text: "Ensure that the Container Network Interface file
  ownership is set to root:root (Manual)"

This fixes these warnings.
