First pass at a non-rook-managed Ceph cluster. We call it k0 instead of
ceph-waw4, as we pretty much are sure now that we will always have a
one-kube-cluster-to-one-ceph-cluster correspondence, with different Ceph
pools for different media kinds (if at all).
For now this has one mon and spinning rust OSDs. This can be iterated on
to make it less terrible with time.
See b/6 for more details.

We want to be able to scrape controller-manager and scheduler metrics
into Prometheus. For that, each of them needs to:
1) listen on a secure port
2) have authn enabled
With this, any k8s user with the right permissions (and a bearer token
or TLS certificate) can come in and access metrics over a node's public
IP address. Access without a certificate/token gets thrown into the
system:anonymous user, which as no access to any API.

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.
