Support Nomad

[analytically]

Would be great if it supported Nomad out of the box too - https://www.nomadproject.io/

Great idea! I don't know enough about Nomad to put this together, but if someone from the community wants to give this a go, I'd be more than happy to talk through an integration!

@brancz , I don't have any experience in Nomad but it is almost an alternative to Kubernetes and mostly integrates to other HashiCorp products like Terraform. Though, I don't have any experience in Nomad, I would like to work on it and explore more, if possible.

Ever since we introduced system-wide profiling in Parca Agent we are already profiling processes in Nomad as we just profile every process on a machine. What would be left to do though is attach metadata. I think we should first gather from Nomad users, what some useful metadata would be.

I think this issue belongs to the agent side. If we add Nomad support, it should be another metadata service discovery implementation like Kubernetes and systemd. https://github.com/parca-dev/parca-agent/tree/main/pkg/discovery

Let's move it to the agent project if everyone agrees.

Agreed
