ops, cluster: consolidate NixOS provisioning

This moves the diff-and-activate logic from cluster/nix/provision.nix
into ops/{provision,machines}.nix that can be used for both cluster
machines and bgpwtf machines.

The provisioning scripts now live per-NixOS-config, and anything under
ops.machines.$fqdn now has a .passthru.hscloud.provision derivation
which is that script. When ran, it will attempt to deploy onto the
target machine.

There's also a top-level tool at `ops.provision` which builds all
configurations / machines and can be called with the machine name/fqdn
to call the corresponding provisioner script.

clustercfg is changed to use the new provisioning logic.

hscloud is the main monorepo of the Warsaw Hackerspace infrastructure code.

Getting started

See //doc/codelabs for tutorials on how to use hscloud.

If you want to browse the source of hscloud in a web browser, use cs.hackerspace.pl.

If you want some other help, talk to q3k, informatic or your therapist.

Directory Structure

Directories you should care about:

  • app: external services that we host that are somewhat universal: matrix, covid-formity, etc.
  • bgpwtf: code related to our little ISP
  • cluster: code related to our Kubernetes cluster (k0.hswaw.net)
  • dc: code related to datacenter automation
  • devtools: code related to developer tooling, like gerrit or hackdoc
  • doc: high-level documentation that doesn't fit anywhere else, ie. codelabs
  • hswaw: Warsaw Hackerspace specific/internal services. The line between this and app is unfortunately blurry.
  • personal: user's personal (experimental) directories
  • kube, go: code specific to languages but general to the whole of hscloud

Licensing

Unless noted otherwise, code in hscloud is licensed under the BSD 0-clause license - see COPYING.
