* 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 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

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.

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.

This avoids spurious failure with 'localhost'.
It should also be more correct the inventory contains uncached hosts
which are not in `k8s_cluster` and therefore should not be Kubespray
business.
(We still use hostvars for uncached hosts, because it's easier to select
on 'ansible_default_ipv4' that way and does not change the end result)
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.
This is needed for shutdown ordering: while at startup, it's not a
problem that containerd start before dbus (the dbus socket already
exists) it needs to shutdown before dbus to do its cleanup (asking
systemd via dbus to cleanup cgroups).
