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

* 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

* 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
