The new version brings the following improvements:
- remove having to resort to python python to limit tags (it it slower than
the sh equivalent as python has a somewhat significant startup time).

- Introduce a concept of min version so that it can only get Kubernetes
version supported by Kubespray.

- Fix an issue with kata changing their file scheme (the arch
  specifically)

- Now download sha256/sha256sum files if provided rather than
  downloading the full file and computing the hash

- A few minor style tweaks

As they're no longer in kubernetes-sigs org.

Since they are no longer in the kubernetes-sigs organization, they can
no longer be assigned PR to approve.

Fixes bug for retrieving images with tags containing image digests.
Script now gets images from jobs and cronjobs as well.
New env variable DESTINATION_REGISTRY to push to another registry
instead of local registry.
New env variable IMAGES_FROM_FILE to pull images listed in a file
instead of getting images from a running k8s environment.
New env variable REGISTRY_PORT to override port (default is 5000).

Should fix GPG errors in CI

Under the original code, leader election failed for ingress controllers
as a result of mismatch between election-id in the controller config,
and the resourceName in the relevant rule of role 'ingress-nginx'.
This appeared in the controller logs.

To fix the issue, a command-line option was added to container
execution (--election-id=...).

Now, the election-id agrees with the resourceName provided in
the role-ingress-nginx.yml file. A comment in that file was
changed to reflect the new logic.

* containerd: Remove redundant 'default' filters

* containerd: enable 'discard_unpacked_layers' by default

This should help with containerd disk usage

This should avoid permissions problems when the user creating the
directory and the user creating the content are different (when
containers images are saved by root for instances, because the user
can't use the container runtime).

The `assert` module does not connect to the host anyway, and this avoids
skipping the assert when running with --limit.

* Refactor of kubeadm images listing

Instead of setting multiples facts, we directly create the dict we need from
kubeadm output.

* Remove useless 'default' filters in roles/download

* Only download kubeadm images where needed

The current state waiting method is bad to implement.
When changing the deployment version, which is execute with the upgrade_cluster in the previous ansible task: "Kubernetes Apps | Install and configure MetalLB", next ansible task: "Kubernetes Apps | Wait for MetalLB controller to be running" may fall with an error.

This reverts commit c6e5314f.

There is no user of the download mirrors support in kubespray, for a
long time.
