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.

This port was leaking kubelet state, including information on running
pods. No secrets were leaked (if they were not text-pasted into
env/args), but this still shouldn't be available.
As far as I can tell, nothing depends on this port, other than some
enterprise load balancers that require HTTP for node 'health' checks.

Prodaccess/Prodvider allow issuing short-lived certificates for all SSO
users to access the kubernetes cluster.
Currently, all users get a personal-$username namespace in which they
have adminitrative rights. Otherwise, they get no access.
In addition, we define a static CRB to allow some admins access to
everything. In the future, this will be more granular.
We also update relevant documentation.
