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.
