Configures an experimental setup for a builderball-based public cache.
This cache only includes the two build machines (whitby & nevsky), for the time
period where both of them exist simultaneously.
The idea is this:
All participating hosts run a harmonia binary cache locally (whitby already
does). They then run builderball instances pointing at each other's harmonia
caches (through dedicated public hostnames).
When a request comes in, the first matching cache address is returned and Nix
will substitute from there.

Harmonia is, ostensibly, faster and better and, most importantly, not a giant
pile of wonky Perl.
I've tested locally that Harmonia works with Nix 2.3 (on both ends), so I think
we should be good to go here.
We have a vendored copy of the upstream module for now. We need to fix Nix 2.3
compatibility in upstream for the module, but the service itself works fine.

The priority of binary caches is decided by the remotes in Nix (???),
and by default nix-serve (which is *very* slow) has a lower priority
than cache.nixos.org (which means that it will be preferred over the
faster cache for paths that exist on both).
To avoid this, override the hardcoded (????) priority by serving the
nix-cache-info response directly from nginx instead.

Splits //ops/nixos into:
* //ops/nixos.nix - utility functions for building systems
* //ops/machines - shared machine definitions (read by readTree)
* //ops/modules - shared NixOS modules (skipped by readTree)
This simplifies working with the configuration fixpoint in whitby, and
is overall a bit more in line with how NixOS systems in user folders
currently work.
