* Add KubeSchedulerConfiguration for k8s 1.19 and up
With release of version 1.19.0 of kubernetes KubeSchedulerConfiguration
was graduated to beta. It allows to extend different stages of
scheduling with profiles. Such effect is achieved by using plugins and
extensions.
This patch adds KubeSchedulerConfiguration for versions 1.19 and later.
Configuration is set to k8s defaults or to kubespray vars. Moving those
defaults to new vars will be done in following patch.

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.

While at it remove force_certificate_regeneration
This boolean only forced the renewal of the apiserver certs
Either manually use k8s-certs-renew.sh or set auto_renew_certificates

The important action in kubeadm-version.yml is the templating of the configuration,
not finding / setting the version

kubeadm is the default for a long time now,
and admin.conf is created by it, so let kubeadm handle it

Using `kubeadm init phase kubeconfig all` breaks kubelet client certificate rotation
as we are missing `kubeadm init phase kubelet-finalize all` to point to `kubelet-client-current.pem`
kubeconfig format is stable so let's just use lineinfile,
this will avoid other future breakage
This revert to the logic before 6fe2248314

On CentOS 8 they seem to be ignored by default, but better be extra safe
This also make it easy to exclude other network plugin interfaces

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

* Move proxy_env to kubespray-defaults/defaults
There is no reasons to use set_facts here

* 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

By default Ansible stat module compute checksum, list extended attributes and find mime type
To find all stat invocations that really use one of those:

Only checking the kubernetes api on the first master when upgrading is not enough.
Each master needs to be checked before it's upgrade.

In some environments, it might not be possible to ping the IP address
of the nodes, e.g., because ICMP echo is blocked.
This commit allows kubespray to be configured to disable the ping
check, while performing all other checks.
