Turns out etcd-only nodes were never running **any** of the controllers,
so allowing multiple controllers didn't really fix things.

Also, use panic instead of Fatalf so that the CloudControllerManager rescue can handle the error

* Bump etcd to v3.5.4-k3s1
* Fix issue with datastore corruption on cluster-reset
* Disable unnecessary components during cluster reset
Disable control-plane components and the tunnel setup during
cluster-reset, even when not doing a restore. This reduces the amount of
log clutter during cluster reset/restore, making any errors encountered
more obvious.

Reuse the existing etcd library code to start up the temporary etcd
server for bootstrap reconcile. This allows us to do proper
health-checking of the datastore on startup, including handling of
alarms.

In rke2 everything is a static pod so this causes a chicken and egg situation
in which we need the kubelet running before the kube-apiserver can be
launched. By starting the apiserver in the background this allows us to
do this odd bootstrapping.
