* preinstall: generalize minimum-value semantics for managed sysctls
Move the hardcoded sysctl floor map out of 0080-system-configurations.yml
into a default variable, and introduce additional_sysctl_min so users can
declare their own sysctl floors. Floor semantics only apply a managed
value when the node's current value is lower; pre-tuned images (Bottlerocket,
EKS AMIs, OpenShift RHCOS, hardened distros) and newer kernels that
already set higher values are left alone.
Default floors are aligned with prior art from the OpenShift Node Tuning
Operator (TuneD '=>' floor syntax in the openshift / openshift-node
profiles) and kops. None of the floor keys are part of the kubelet
protect-kernel-defaults validation list, so the floor mechanism cannot
interfere with kubelet startup. Keys not present on the running
kernel/distro are skipped without failing.
additional_sysctl (exact-value semantics) is unchanged for backward
compatibility.

* preinstall: refine sysctl floor handling
Keep built-in floor values internal while preserving user overrides
through additional_sysctl_min.
Use sysctl --ignore for unknown keys and filter empty results without
masking other read errors.

- also remove mitogen workaround from local_volume_provisioner since
creating the dirs is handled by kubernetes/preinstall instead
- correct the tag in kubernetes/preinstall as persistent_volumes isn't
the same thing
- Updated download URLs to fetch the kata-static<...>.zst files from github repo.
- Added zstd package in kata-continers role.
- Updated version checksums to match the new release files.
Moved zstd dependency to roles/system_package
* Reboot only when required, add the option to clean packages.
* Update docs to reflect only Debian based distribution can be apt
autocleaned
* Add apt cleanup to upgrade tests
The Cilium Helm chart appends a -generic suffix to the operator image
repository for non-cloud deployments. Sync the operator-generic image
to offline registries so it matches what the chart requests.

* [etcd] Update etcd 3.5.x to 3.6.5
- Add hashes for etcd 3.6.5
- Remove etcd v2 backup task for etcd 3.6
The etcd 3.6 removes 'etcdctl backup' command with ETCDCTL_API=2
- Downgrade etcd to 3.5 in netchecker
The netchecker does not work with etcd 3.6 becaust it removes v2 API support (--enable-v2).
And netchekcer does not support v3 API.
* Fix: Change etcd config to clean up v2 store before upgrading etcd to 3.6
* Bump etcd to 3.6.8

Since we're not longer injecting pseudo DNS into /etc/hosts,
'lb-apiserver.kubernetes.local' (the previous default) won't resolve to
anything.
Instead, default to the loadbalancer IP if defined, or to the node local
loadbalancer if it's in use.
Make the necessary adjustements in use site to deal with ip addresses as
well as hostnames.
When loadbalancer_apiserver_localhost is enabled, Calico falls back to the
Kubernetes service IP because the kubernetes-services-endpoint ConfigMap is
empty. CNI then fails to reach the API server even though an nginx proxy is
listening on localhost.
Update kube_apiserver_global_endpoint to always reference the localhost load
balancer (respecting the configured port) and populate the ConfigMap for both
eBPF and localhost LB modes.
* control-plane: fix first_kube_control_plane delegation with kube_override_hostname
When kube_override_hostname is configured, the node names reported by
`kubectl get nodes` differ from the inventory_hostname known to Ansible.
This causes delegation failures in subsequent tasks since Ansible cannot
resolve the hostname from kubectl output to an inventory host.

* control-plane: remove fragile first_control_plane selection logic
Current implementation breaks with kube_override_hostname and has
multiple edge cases. Drop until proper kubectl-based node lookup
can be implemented.
