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.

* Add crun download_url and checksum

* Change versioning format to crun native versioning

* Download crun using download_file.yml

* Get crun version from download defaults

* Delegate crun binary copy task to crun role

* Download Calico KDD CRDs

* Replace kustomize with lineinfile and use ansible assemble module

* Replace find+lineinfile by sed in shell module to avoid nested loop

* add condition on sed

* use block for kdd tasks + remove supernumerary kdd manifest apply in start "Start Calico resources"

Since a790935d 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 1c5391dd

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

* update Cinder CSI to v1.19.0

* Update Cinder CSI to v1.20

* 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:
git grep -F stat. | grep -vE 'stat.(islnk|exists|lnk_source|writeable)'
