I like running fail2ban on any machine that has stuff like ssh
world-open, to limit the potential for password brute-force attacks etc.

Points clbot at the new local ZNC instead. This will make it part of

This adds a shadowsocks service, running on port 8443, tcp and udp.
The password is read from /etc/secrets/shadowsocks-secret.sec, and needs
to be populated externally.

Adds a module that automatically collects garbage based on disk space
thresholds, and configures it to run hourly on whitby.
This is implemented as an alternative to cl/2937, which I've been told
uses a Nix feature that doesn't actually work.
Under-the-hood this is simply a systemd timer running a shell script
which checks available disk space and runs GC when necessary.

There's a hard-coded list of Admin usernames for the moment. We should

Enables a Grafana service pointing to whitby's local Prometheus
instance, accessible at status.tvl.su.
I've no idea how to configure Grafana and if it's possible to link it
to CAS, but we'll see about that later.
Notes:
* the explicit fixpoint for whitby config has been removed as we
have the `config` parameter available now
* backups are enabled for the Grafana storage location

Instead of having two ways of accessing the path to the depot (one of
which was stuttering, depot.depotPath) we settle on only one:
depot.path.
This was mostly used for NixOS module imports.

Enables Prometheus with a local node exporter, and nothing else for
now.
Some additional collectors have been enabled for things that might be
relevant on whitby:
* systemd: all our services run in systemd
* processes: might be interesting for build-related stats
* logind: might be interesting for interactive usage stats

This may require some extra attention inside of gerrit's database after

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.
