Improve first_kube_control_plane variable management to avoid installation failures due to variable overlapping (#8388)

Fix container engine still installed on dedicated etcd node even if `etcd_deployment_type: host` (#8386)

All container image versions were defined in download/defaults/main.yml
except containerd.
The inconsistency caused the offline script(generate_list.sh) could not
output the URL of containerd image.
This moves the definition into a valid file.
In addition, this adds host_os to generate_list.sh for downloading
krew from a valid URL.

* Add kubectl variable

* Replace kubectl usage by kubectl variable in roles

* Remove redundant --kubeconfig on kubectl usage

* Replace unecessary shell usage with command

* containerd: change default resolvconf_mode to host_resolvconf

* Wait for kube-apiserver to come back after pod refresh

* Handle resolv.conf gracefully

* Retain currently configured DNS entries to ensure we don't break the resolvers

* Suse uses wickedd for network management so no dhcp hooks

* Molecule: increase ansible timeout

* CI: Increase ansible timeout to 120s for Packet jobs

* Improve control plane scale flow (#13)

* Added version 1.20.10 of K8s

* Setting first_kube_control_plane to a existing one

* Setting first_kube_control_plane to a existing one

* change first_kube_master for first_kube_control_plane

* Ansible-lint changes

* if bind-address is not set to 0.0.0.0

* Update docs and left comments

* fix yamllist check: remove space

* containerd: add hashes for 1.5.8 and 1.4.12 and make 1.5.8 the new default

* containerd: make nerdctl mandatory for container_manager = containerd

* nerdctl: bump to version 0.14.0

* containerd: use nerdctl for image manipulation

* OpenSuSE: install basic nerdctl dependencies

* Defaults: replace docker with containerd as our default container_manager

* CI: Use docker for download_localhost test

* Defaults: with container_manager=containerd we need etcd_deployment_type=host

* CI: Run weave jobs with docker

* CI: Vagrant don't download_force_cache

* CI: Fix upgrade tests

* should run compatible with old settings, this means docker
* we need to run with a distro that has at least modern containerd,
  this means move from debian9 to debian10 to allow `containerd_version`
  to match between 2.17 and master

* nodelocaldns: allow a secondary pod for nodelocaldns for local-HA

* CI: add job to test nodelocaldns secondary

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.

* Added ArgoCD kubernetes-app

* Update argocd_version to latest

* Fix containerd install for fcos

* rm orphaned runc and containerd binaries

If the etcd cluster is separate and the etcd_deployment_type is "host",
there is no need for a container engine on the etcd nodes

Do not rely on a 'default(true)' filter, but define a proper default in
kubespray-defaults depending on etcd deployment method and if internal
or external etcd is used

* Add kubeadm_join_phases_skip variable

* Update kubeadm_join_phases_skip comment
