Add possibility to use systemdspawner as non-root

[Frank-Steiner]

Hi,
is there any chance to add sth. like the nonrootv2 feature to systemdspawner?

Being able to have juypterhub run as non-root is the only reason for the sudo spawner, which misses all the config options that systemdspawner has. The mechanism in Joergs nonrootv2 tree adds a very systemd'ish way to use per-user service file instances.

Have you considered adding this? Would be great to have systemdspawner + non-root...
cu,
Frank

Interesting you should mention that. I've recently deployed JupyterHub again and in the course redid some of the stuff around my earlier branch for running JupyterHub without root. I wanted to clean up the history and open a PR for that next week, closing the old one. Alternatively I'm considering a friendly fork under a different name, since I've added named servers and intend to add a few more features, but I'm also using newer systemd features like the credentials mechanism.

Would be great to either have it added to the default systemdspawner or have some other spawner that could be installed as easy as the others ones like "pip install jupyterhub-systemdnonrootspawner". Looking forward to testing whatever you come up with :)

@Frank-Steiner it's not much, but I opened #100 to start a discussion.
