Document pattern for multiple workers via systemd

[anseljh]

Hello! I'm wondering if there's a solid pattern people are using for starting up multiple workers under systemd. I'm happy to help write up a page for the docs if there is.

I run multiple RQ instances via systemd template unit files. I have a template named rqworker@.service which allows me to spin up additional workers by calling systemctl start rqworker@one.service, systemctl start rqworker@two.service etc.

All of them can also be reloaded by calling systemctl reload rqworker@*.

If you can, please open a PR for this.

Thanks! That's the solution I ended up on as well, so it's nice to have some validation. I will open a PR, but probably won't get to it for a few weeks.
