localhost.run tunnel as a systemd service

Download the localhost.run.service file.
Rename it to localhost.run-${domain}@${port}.service, replacing ${domain} with either localhost.run or your custom domain or subdomain and ${port} with the local port your webapp listens on for this and all the following steps.
hint: You can set env vars, for eg: domain=example.com port=8080, for "it just works"™️ copy-pasting action.
Create a user systemd folder by running mkdir -p ~/.config/systemd/user/.
Move your renamed file into ~/.config/systemd/user/.
Run systemctl --user enable localhost.run-${domain}@${port}.service to enable your service on startup.
Run systemctl --user start localhost.run-${domain}@${port}.service to start your service.

The service will generate a key into ~/.ssh/localhost.run.${domain}-${port}.rsa if one doesn't already exist there.

It writes the tunnels address into /tmp/localhost.run.${domain}-${port}.address.

You can check service logs by running journalctl --user -u localhost.run-${domain}@${port}.service

PRs are very, very welcome, but pls try to keep the service file as self contained as possible. This means simple commands that exist on most hosts.
