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

* 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.

Several types contained redundant references to ControlRuntime data. Switch to consistently accessing this via config.Runtime instead.

* Always use static ports for the load-balancers
This fixes an issue where RKE2 kube-proxy daemonset pods were failing to
communicate with the apiserver when RKE2 was restarted because the
load-balancer used a different port every time it started up.
This also changes the apiserver load-balancer port to be 1 below the
supervisor port instead of 1 above it. This makes the apiserver port
consistent at 6443 across servers and agents on RKE2.
Additional fixes below were required to successfully test and use this change
on etcd-only nodes.
* Actually add lb-server-port flag to CLI
* Fix nil pointer when starting server with --disable-etcd but no --server
* Don't try to use full URI as initial load-balancer endpoint
* Fix etcd load-balancer pool updates
* Update dynamiclistener to fix cert updates on etcd-only nodes
* Handle recursive initial server URL in load balancer
* Don't run the deploy controller on etcd-only nodes
* Add functionality for etcd snapshot/restore to and from S3 compatible backends.
* Update etcd restore functionality to extract and write certificates and configs from snapshot.
* Set etcd timeouts using values from k8s instead of etcdctl
Fix for one of the warnings from #2303
* Use etcd zap logger instead of deprecated capsnlog
Fix for one of the warnings from #2303
* Remove member self-promotion code paths
* Add learner promotion tracking code
* Fix RaftAppliedIndex progress check
* Remove ErrGRPCKeyNotFound check
This is not used by v3 API - it just returns a response with 0 KVs.

According to @galal-hussein this is dead code that was probably brought
over from Kine. I certainly couldn't figure out what it is supposed to
be doing.

This attempts to update logging statements to make them consistent
through out the code base. It also adds additional context to messages
where possible, simplifies messages, and updates level where necessary.
