* node: fix default kubelet/runtime cgroups when kube_reserved is false (default)
Commit 1c4db6132d introduced a notion of
kube_reserved. This introduced a breaking change defaulting to use
kube.slice for the container_manager and the kubelet as if kube_reserved
was always enabled whereas it is disabled by default.
This commit fixes this by bringing back system.slice whenever
kube_reserved is disabled.

* network_plugin/custom_cni: add CNI to apply provided manifests
Add a new simple custom_cni to install provided Kubernetes manifests.
This could be useful to use manifests directly provided by a CNI when
there are not support by Kubespray (i.e.: helm chart or any other manifests
generation method).

This commit uses a kubeadm join config to pull down cert for etcd in
workers nodes (which is needed in some circumstances, for instance with
calico or cilium).
The previous way didn't allow us to pass certain parameters which was
typically given in the config in other kubeadm invokations in Kubespray.
This made kubeadm produced some errors for some edge cases.
For example, in our deployment we don't have a default route and even
though it's only to download the certificates, kubeadm produce an error
`unable to select an IP from default routes` (these command are kubeadm
controlplane command, so kubeadm does some additional checks). This is
fixed by specifying `advertiseAddress` within the kubeadm config.

configured will receive the admission plugin treatment.
* Fix the PR according to code review comments
* Revert the latest changes
- leave the empty file when kube_pod_security_use_default, but add comment explaining the empty file
- don't attempt magic at conditionally adding PodSecurity to kube_apiserver_admission_plugins_needs_configuration
The commit 1ce2f04 tried to merge multiple SUSE OS checks including
"openSUSE Leap" and "openSUSE Tumbleweed" into a single SUSE, but
that was a perfect change.
Then the commit c16efc9 tried to fix it for "openSUSE Leap", but it
didn't take care of "openSUSE Tumbleweed".
Then this adds "openSUSE Tumbleweed" to the OS check.

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.
