- we update NixOS to 20.09pre
- we fix an ACME option that's now required
- we switch from systemd-timesyncd to chrony (as timesyncd took a long
time to sync clocks after restart, leading to MON_CLOCK_SKEW errors
from ceph)
This has been deployed in production.

We change the existing behaviour (copy files & run nixos-rebuild switch)
to something closer to nixops-style. This now means that provisioning
admin machines need Nix installed locally, but that's probably an okay
choice to make.
The upside of this approach is that it's easier to debug and test
derivations, as all data is local to the repo and the workstation, and
deploying just means copying a configuration closure and switching the
system to it. At some point we should even be able to run the entire
cluster within a set of test VMs.
We also bump the kubernetes control plane to 1.14. Kubelets are still at
1.13 and their upgrade is comint up today too.
