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.

Fix kubelet_kubelet_cgroups_cgroupfs (#8500)
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.

Replace kube-master with kube_control_plane (#7256)
This replaces kube-master with kube_control_plane because of [1]:

  The Kubernetes project is moving away from wording that is
  considered offensive. A new working group WG Naming was created
  to track this work, and the word "master" was declared as offensive.
  A proposal was formalized for replacing the word "master" with
  "control plane". This means it should be removed from source code,
  documentation, and user-facing configuration from Kubernetes and
  its sub-projects.

NOTE: The reason why this changes it to kube_control_plane not
      kube-control-plane is for valid group names on ansible.

Fix proxy usage when *_PROXY are present in environment (#7309)
Since a790935d02 all proxy users
should be properly configured

Now when you have *_PROXY vars in your environment it can leads to failure
if NO_PROXY is not correct, or to persistent configuration changes
as seen with kubeadm in 1c5391dda7

Instead of playing constant whack-a-bug, inject empty *_PROXY vars everywhere
at the play level, and override at the task level when needed

Signed-off-by: Etienne Champetier <e.champetier@ateme.com>

* Ensure kubeadm doesn't use proxy

*_proxy variables might be present in the environment (/etc/environment, bash profile, ...)
When this is the case we end up with those proxy configuration in /etc/kubernetes/manifests/kube-*.yaml manifests

We cannot unset env variables, but kubeadm is nice enough to ignore empty vars
