Fix issue with datastore corruption on cluster-reset (#5515)
* 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.

c707948adf netpol: Add dual-stack support
This change allows to define two cluster CIDRs for compatibility with
Kubernetes dual-stuck, with an assumption that two CIDRs are usually
IPv4 and IPv6.

It does that by levearaging changes in out kube-router fork, with the
following downstream release:

dc18ef2e51 Refactor log and reaper exec to omit MAINPID
Using MAINPID breaks systemd's exit detection, as it stops watching the
original pid, but is unable to watch the new pid as it is not a child
of systemd itself. The best we can do is just notify when execing the child
process.

We also need to consolidate forking into a sigle place so that we don't
end up with multiple levels of child processes if both redirecting log
output and reaping child processes.

a84c75af62 Adds a command-line flag '--disable-helm-controller' that will disable
the server's built-in helm controller.

Problem:
Testing installation and uninstallation of the Helm Controller on k3s is
not possible if the Helm Controller is baked into the k3s server.

Solution:
The Helm Controller can optionally be disabled, which will allow users
to manage its installation manually.

Always use static ports for client load-balancers (#3026)
* 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
