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.

These were not meant to be enabled by default, break images with many

* cli: add --selinux flag to agent/server sub-cmds
Introduces --selinux flag to affirmatively enable SELinux in containerd.
Deprecates --disable-selinux flag which now defaults to true which
auto-detection of SELinux configuration for containerd is no longer
supported. Specifying both --selinux and --disable-selinux will result
in an error message encouraging you to pick a side.
* Update pkg/agent/containerd/containerd.go
update log warning message about enabled selinux host but disabled runtime
