Now `docker run -p` ports can be exposed to the host namespace automatically when `dockerd-rootless.sh` is launched with
`--userland-proxy --userland-proxy-path $(which rootlesskit-docker-proxy)`.
This is akin to how Docker for Mac/Win works with `--userland-proxy-path=/path/to/vpnkit-expose-port`.
The port number on the host namespace needs to be set to >= 1024.
SCTP ports are currently unsupported.

Please refer to `docs/rootless.md`.
TLDR:
* Make sure `/etc/subuid` and `/etc/subgid` contain the entry for you
* `dockerd-rootless.sh --experimental`
* `docker -H unix://$XDG_RUNTIME_DIR/docker.sock run ...`
