This allows secondary etcd nodes to bootstrap the kubelet before an
apiserver joins the cluster. Rancher waits for all the etcd nodes to

Before this change, we were copying a part of kube-router code to
pkg/agent/netpol directory with modifications, from which the biggest
one was consumption of k3s node config instead of kube-router config.
However, that approach made it hard to follow new upstream versions.
It's possible to use kube-router as a library, so it seems like a better
way to do that.
Instead of modifying kube-router network policy controller to comsume
k3s configuration, this change just converts k3s node config into
kube-router config. All the functionality of kube-router except netpol
is still disabled.

Since we now start the server's agent sooner and in the background, we
may need to wait longer than 30 seconds for the apiserver to become
ready on downstream projects such as RKE2.
Since this essentially just serves as an analogue for the server's
apiReady channel, there's little danger in setting it to something
relatively high.

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.

* Fix URL pruning when joining an etcd member
Problem:
Existing member clientURLs were checked if they contain the joining
node's IP. In some edge cases this would prune valid URLs when the
joining IP is a substring match of the only existing member's IP.
Because of this, it was impossible to e.g. join 10.0.0.2 to an existing
node that has an IP of 10.0.0.2X or 10.0.0.2XX:
level=fatal msg="starting kubernetes: preparing server: start managed database:
joining etcd cluster: etcdclient: no available endpoints"
Solution:
Fixed by properly parsing the URLs and comparing the IPs for equality
instead of substring match.

Problem:
Only the client CA is passed to the kube-controller-manager and
therefore CSRs with the signer name "kubernetes.io/kubelet-serving" are
signed with the client CA. Serving certificates must be signed with the
server CA otherwise e.g. "kubectl logs" fails with the error message
"x509: certificate signed by unknown authority".
Solution:
Instead of providing only one CA via the kube-controller-manager
parameter "--cluster-signing-cert-file", the corresponding CA for every
signer is set with the parameters
"--cluster-signing-kube-apiserver-client-cert-file",
"--cluster-signing-kubelet-client-cert-file",
"--cluster-signing-kubelet-serving-cert-file", and

Now rootless mode can be used with cgroup v2 resource limitations.
A pod is executed in a cgroup like "/user.slice/user-1001.slice/user@1001.service/k3s-rootless.service/kubepods/podd0eb6921-c81a-4214-b36c-d3b9bb212fac/63b5a253a1fd4627da16bfce9bec58d72144cf30fe833e0ca9a6d60ebf837475".
This is accomplished by running `kubelet` in a cgroup namespace, and enabling `cgroupfs` driver for the cgroup hierarchy delegated by systemd.
To enable cgroup v2 resource limitation, `k3s server --rootless` needs to be launched as `systemctl --user` service.
Please see the comment lines in `k3s-rootless.service` for the usage.
Running `k3s server --rootless` via a terminal is not supported.
When it really needs to be launched via a terminal, `systemd-run --user -p Delegate --tty` needs to be prepended to create a systemd scope.

* 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.

* Fix nil pointer when starting server with --disable-etcd but no --server
* Don't try to use full URI as initial load-balancer endpoint
