* Cleanup: kubeadm-config v1beta4 extra args defined conditions
Some variables have already been defined, so there is no need to
useconditional statements to check whether they have been defined.

When installing or upgrading in the past, there was no validation
config. Check if the file exists first to prevent subsequent validation
errors.

The validation step is moved to the end to avoid the loss of files that
may lead to verification failure.

* Fix: check expiraty before renew
Since certificate renewal and container restarts involve higher risks,
they should be executed with extra caution.

* Remove tag master
Following it's deprecation in 4b324cb0f (Rename master to control plane
- non-breaking changes only (#11394), 2024-09-06)
* Add fail fast path when using removed tags
- Used for the master tag, but this could be used for other things in
the future
The preinstall assert cover a number of things, many of which depends
only on the inventory, and can be run without any ansible_facts
collected.
Split them off to simplify re-ordering.
* Refactor control plane upgrades with reconfiguration support
Adds revised support for:
- The previously removed `--config` argument for `kubeadm upgrade apply`
- Changes to `ClusterConfiguration` as part of the `upgrade-cluster.yml` playbook lifecycle
- kubeadm-config `v1beta4` `UpgradeConfiguration` for the `kubeadm upgrade apply` command: [UpgradeConfiguration v1beta4](https://kubernetes.io/docs/reference/config-api/kubeadm-config.v1beta4/#kubeadm-k8s-io-v1beta4-UpgradeConfiguration).
* Add kubeadm upgrade node support
Per discussion:
- Use `kubeadm upgrade node` on secondary control plane upgrades
- Add support for UpgradeConfiguration.node in kubeadm-config.v1beta4
- Remove redundant `allowRCUpgrades` config
- Revert from `block` for first and secondary control plane back to unblocked tasks since they no longer share much code and it's more readable this way
* Add kubelet and kube-proxy reconfiguration to upgrades
* Fix task to use `kubeadm init phase etcd local`
* Rebase with changes from "Adapt checksums and versions to new hashes updater" PR
* Add `imagePullPolicy` and `imagePullSerial` to kubeadm-config v1beta4 `InitConfiguration.nodeRegistration`
* 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
The versions which are by default derived from `kube_version` can break
the assert if kube_version start with `v`, because they use the start of
`kube_version` as dict key.
By putting them in their own assert, the first assert should trigger on
`kube_version`, with a more explicit error.
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.
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.
