Add SLURM cgroups support to system.go

Thanks! Adding support for cgroups is a big help, but we might want to separate this functionality into its own package and use it only if the system supports reading from cgroup.

Looks like a lot of stuff was removed here that we need to keep (sensors, gpu, etc.).

I need to work on some high priority things for the next release but I'll get back to you after that. Probably next week.

Yeah, this code was a proof of concept to see if it would even work.

If I can do more to help, do let me know, I want to use this to run per job node monitoring in hpc clusters.

I wonder if this could be used to add support for monitoring Systemd services as well as containers?

I think so yes, as those are generally started within their own cgroup.
So that would enable beszel to monitor just the resources assigned to such services and containers.

For what it's worth, this would catapult Beszel from "almost useless" to "really good" for me — since I use a NixOS server and most applications are managed as nix-provided systemd services instead of containers.

Friendly poke @henrygd 🙂

As mentioned above, this looks really cool to me due to the capability to monitor systemd services. If you are able to spare the time to give this a good look, that would be great!

I made a new version that i'm testing out, if it works well, i'll make another Pull Request.

Thanks, if the feature can be more isolated (like in its own package) then I should be able to get to it more quickly.

I've had less spare time this year and more requests for support, so I'm behind where I hoped I'd be as far as development. We will get there eventually.

Hey @MichaelAronsen, just a gentle poke, it would be cool to hear how your revised effort went 🙂
