Remove --auth-anonymous if kube_api_anonymous_auth in undefined, to avoid
compatibility errors with other arguments of the kube-apiserver, such as
--authentication-config when anonymous field is configured.

* Ensure correct `AuthorizationConfiguration` API version during upgrades
Fixes an issue where the wrong AuthorizationConfiguration API version could be used by kube-apiserver prematurely during upgrades.
The `kubernets/control-plane` role writes configuration for the target version before control plane pods are upgraded.
However, since the `AuthorizationConfiguration` file is reconciled continuously, this leads to a race condition where a new configuration version can be reconciled before kube-apiserver is upgraded to the compatible version.
This solution ensures the correct configuration is available throughout the process by writing each api version to a different file path. Unused file versions are cleaned up post-upgrade for better hygiene.
* Avoid from_json in cleanup task
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.
* 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 a142f40e2 (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
* [kubernetes] Support Kubernetes v1.32.0
* add workaround for RHEL8

Adds the ability to configure the Kubernetes API server with a structured authorization configuration file.
Structured AuthorizationConfiguration is a new feature in Kubernetes v1.29+ (GA in v1.32) that configures the API server's authorization modes with a structured configuration file.
AuthorizationConfiguration files offer features not available with the `--authorization-mode` flag, although Kubespray supports both methods and authorization-mode remains the default for now.
Note: Because the `--authorization-config` and `--authorization-mode` flags are mutually exclusive, the `authorization_modes` ansible variable is ignored when `kube_apiserver_use_authorization_config_file` is set to true. The two features cannot be used at the same time.
Docs: https://kubernetes.io/docs/reference/access-authn-authz/authorization/#configuring-the-api-server-using-an-authorization-config-file
Blog + Examples: https://kubernetes.io/blog/2024/04/26/multi-webhook-and-modular-authorization-made-much-easier/
KEP: https://github.com/kubernetes/enhancements/tree/master/keps/sig-auth/3221-structured-authorization-configuration
I tested this all the way back to k8s v1.29 when AuthorizationConfiguration was first introduced as an alpha feature, although v1.29 required some additional workarounds with `kubeadm_patches`, which I included in example comments.
I also included some example comments with CEL expressions that allowed me to configure webhook authorizers without hitting kubeadm 1.29+ issues that block cluster creation and upgrades such as this one: https://github.com/kubernetes/cloud-provider-openstack/issues/2575.
My workaround configures the webhook to ignore requests from kubeadm and system components, which prevents fatal errors from webhooks that are not available yet, and should be authorized by Node or RBAC anyway.

We use a lot of facts where variables are enough, and format too early,
which prevent reusing the variables in different contexts.
- Moves set_fact variables to the vars directory, remove unnecessary
intermediate variables, and render them at usage sites to only do logic
on native Ansible/Jinja lists.
- Use defaults/ rather than default filters for several variables.

The fallback_ips tasks are essentially serializing the gathering of one
fact on all the hosts, which can have dramatic performance implications
on large clusters (several minutes).
This is essentially a reversal of 35f248dff0
Being able to run without refreshing the cache facts is not worth it.
We keep fallback_ip for now, simply changing the access to a normal
hostvars variable instead of a custom dictionnary.
Testing for group membership with group names makes Kubespray more
tolerant towards the structure of the inventory.
Where 'inventory_hostname in groups["some_group"] would fail if
"some_group" is not defined, '"some_group" in group_names' would not.
* Simplify docker systemd unit
systemd handles missing unit by ignoring the dependency so we don't need
to template them.
* Remove RHEL 7/CentOS 7 support
- remove ref in kubespray roles
- move CI from centos 7 to 8
- remove docs related to centos7
* Remove container-storage-setup
Only used for RHEL 7 and CentOS 7
