This adds a new flag with default `kubeadm_config_validate_enabled: true` to use when debugging features and enhancements affected by the `kubeadm config validate command`.

This new flag should be set to `false` only for development and testing scenarios where validation is expected to fail (pre-release Kubernetes versions, etc).

While working with development and test versions of Kubernetes and Kubespray, I found this option very useful.

Adding single quotees around parameters in crictl.

* Automatically derive defaults versions from checksums

Currently, when updating checksums, we manually update the default
versions.
However, AFAICT, for all components where we have checksums, we're using
the newest version out of those checksums.

Codify this in the `_version` defaults variables definition to make the
process automatic and reduce manual steps (as well as  the diff size
during reviews).

We assume the versions are sorted, with newest first. This should be
guaranteed by the pre-commit hooks.

* Validate checksums are ordered by versions, newest first

* Generalize render-readme-versions hook for other static files

The pre-commit hook introduced a142f40e (Update versions in README.md
with pre-commit, 2025-01-21) allow to update our README with new
versions.
It turns out other "static" files (== which don't interpret Ansible
variables) also use the default version (in that case, our Dockefiles,
but there might be others)
The Dockerfile breaks if the variable they use (`kube_version`) is a
Jinja template.

For helping with automatic version upgrade, generalize the hook to deal
with other static files, and make a template out of the Dockerfile.

* Dockerfile: template kube_version with pre-commit instead of runtime

* Validate all versions/checksums are strings in pre-commit

All the ansible/python tooling for version is for version strings. YAML
unhelpfully consider some stuff as number, so enforce this.

* Stringify checksums versions

* Remove krew installation support

Krew is fundamentally to install kubectl plugins, which are eminently a
client side things.
It's also not difficult to install on a client machine.

* Remove krew cleanup

This assertion is present since 2022, users inventories' should be clean
from it now.

This assert is present since 2021, we can assume now users have removed
it from their inventories.

This has been deprecated for a long time, time to pull the plug.
We leave an assert for one release to have a straightforward failure if
some users were still using the variable.

Since 'none' can be, for instance, a manual calico deployment, don't
check whether there is enough ip for pods on a node, because the plugin
can use another mechanism than the podCIDR to allocate IPs.

When the etcd group is not specified we assume it's kube_control_plane.
In that case, etcd still can't be even, so instead of only checking the
etcd group we need to default to kube_control_plane

Upstream calico isn't doing that, and:
- this can cause throttling
- the cpu needed by calico is very cluster / workload dependent
- missing cpu limits will not starve other pods (unlike missing memory
  requests), because the kernel scheduler will still gives priority to
  other process in pods not exceeding their requests
