* Fix: set fallback value of kubelet ip6 (#8858)

This reverts commit e375678674.
The workaround of explicitly specifying root for the kubelet unit was
for pulling images from private registry. Kubernetes now have a
dedicated mechanism with imagePullSecret.
Current Kubespray supports the Kubernetes version 1.21 or upper with
`kube_version_min_required: v1.21.0`
Then kube_version v1.20- related code is not used at all.
This deletes those code for cleanup.

aufs-tools was required for docker.io package originally,
but Kubespray installs docker-ce package instead today.
In addition, Ubuntu 20.04 doesn't provide aufs-tools as [1].
Then this removes aufs-tools from Ubuntu requirement.

If running Kubespray on static IP environments, a task was failed like:
TASK [kubernetes/preinstall : Configure dhclient hooks for resolv.conf (RH-only)]
fatal: [ak8s2]: FAILED! => {
"changed": false, "checksum": "..",
"msg": "Destination directory /etc/dhcp/dhclient.d does not exist"}
This adds a check for dhclientconffile for running 0100-dhclient-hooks to
run the task only if dhcpclient is enabled.
* [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
* 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)
If kubelet is run with systemd (as it always is when using kubespray),
it starts in systemd's /system.slice/kubelet.service cgroup.
This commit prevents a creation and usage of a second unrelated cgroup.

split runc download to separate role
make bootstrap-os role deploy container-selinux and seccomp libraries
clean up package manager provided containerd
move variables to docker role that are no longer common with containerd
* Containerd: make molecule testing more relevant
* replace ubuntu18 with ubuntu20

of test including dependency packages

to remove deprecation warning:

Kubespray deployment failed when using containerd backend on nodes that apparmor was not installed or previously removed. This PR ensure apparmor is installed by adding it into required_pkgs var.

The path of kubeconfig should be configurable, and its default value
is /etc/kubernetes/admin.conf. Most paths of the file are configurable
but some were not. This make those configurable.
* Calico: make calico_min_version check relevant
* Calico: only check currently installed version against the oldest supported version by the previous release
On Debian 11, `ipset` just recommend `iptables` so on the system that apt is configured with `APT::Install-Recommends "0";` iptables will not install automatically.

follow new naming conventions for gcr's coredns image.
starting from 1.21 kubeadm assumes it to be `coredns/coredns`:
this causes the kubeadm deployment being unable to pull image, beacuse `v`
was also added in image tag, until the role `kubernetes-apps` ovverides
it with the old name, which is only compatible with <=1.7.
Backward comptability with kubeadm <=1.20 is mantained checking
kubernetes version and falling back to old names (`coredns:1.xx`) when
the version is less than 1.21
