Allow "openSUSE Tumbleweed" to be run (#9072)
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.

Revert "Set exact user for Kubelet services" (#8872)
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.

Delete kube_version v1.20- related code (#8869)
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.

Remove aufs-tools from Ubuntu requirement (#8754)
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.

Run 0100-dhclient-hooks if dhcpclient is enabled (#8658)
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.
