This commit removes the variable `use_localhost_as_kubeapi_loadbalancer`
and rather detects that we are in a situation where we can use the
localhost apiserver loadbalancer (meaning that we use the localhost load
balancer and that the same ports are used for both the load balancer and
the kube-apiserver).
This also cleanups the calico code to use `kube_apiserver_global_endpoint`
rather than implementing the same logic all over again.

* node: fix default kubelet/runtime cgroups when kube_reserved is false (default)
Commit 1c4db6132d introduced a notion of
kube_reserved. This introduced a breaking change defaulting to use
kube.slice for the container_manager and the kubelet as if kube_reserved
was always enabled whereas it is disabled by default.
This commit fixes this by bringing back system.slice whenever
kube_reserved is disabled.

It is quite confusing that there's an all-caps, bolded comment that seems to imply that `etcd_download_url` is relevant only when not using host-based deployment. The opposite is true: of course the artifact download URL is relevant and required for host-based etcd.
Perhaps the entire comment can be read in a different way, and should perhaps be reworded entirely, cf. 374438a3d6/docs/offline-environment.md?plain=1#L38
Removing the "**DON'T**" matches the way the other comments in this file are written and matches my personal interpretation.
* optimize cgroups settings for node reserved
* fix
* set cgroup slice for multi container engine
* set cgroup slice for crio
* add reserved cgroups variables to sample files
* Compatible with cgroup path for different container managers
* add cgroups doc
* fix markdown
* feat(): Add wireguard backend to flannel cni
As described in the flannel docs:
https://github.com/flannel-io/flannel/blob/master/Documentation/backends.md#wireguard
This does not support optional configuration methods like:
- setting a psk (will be autogenerated by default)
- chang listening ports
- change mode (defaults to 'separate')
- change PersistentKeepaliveInterval (defaults to 0)
* Add supported backends to flannel docs
* Fix markdown in docs
* [metrics_server]: Enabled HA mode by adding 'metrics_server_replicas' variable and adding podAntiAffinity rule
