The kube-apiserver cert should have the same SANs in the same order,
excluding the extra user-configured SANs since this will only be used
in-cluster.

If key ends in "+" the value of the key is appended to previous
values found. If values are string instead of a slice they are
automatically converted to a slice of one string.

Configuration will be loaded from config.yaml and then config.yaml.d/*.(yaml|yml) in
alphanumeric order. The merging is done by just taking the last value of
a key found, so LIFO for keys. Slices are not merged but replaced.

Some of the new node compat tests take a while before failing as
expected. We don't seem to need the additional time any longer to avoid
flakes, so turn it down a bit.

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.

Support repository regex rewrite rules when fetching image content.
Example configuration:
```yaml
# /etc/rancher/k3s/registries.yaml
mirrors:
"docker.io":
endpoint:
- "https://registry-1.docker.io/v2"
rewrite:
"^library/alpine$": "my-org/alpine"
```
This will instruct k3s containerd to fetch content for `alpine` images
from `docker.io/my-org/alpine` instead of the default
`docker.io/library/alpine` locations.

get() is called in a loop until client configuration is successfully
retrieved. Each iteration will try to configure the apiserver proxy,
which will in turn create a new load balancer. Skip creating a new
load balancer if we already have one.

If the port wanted by the client load balancer is in TIME_WAIT, startup
will fail. Set SO_REUSEPORT so that it can be listened on again
immediately.
The configurable Listen call wants a context, so plumb that through as
well.
