q3k ef3aab6a14 k0: host os bump wip
This bumps it on bc01n01, but nowhere else yet.

We have to vendor some more kubelet bits unfortunately.

q3k 55a486ae49 cluster: refactor nix machinery to fit //ops
This is a chonky refactor that get rids of the previous cluster-centric
defs-* plain nix file setup.

Now, nodes are configured individually in plain nixos modules, and are
provided a view of all other nodes in the 'machines' attribute. Cluster
logic is moved into modules which inspect this array to find other nodes
within the same cluster.

Kubernetes options are not fully clusterified yet (ie., they are still
hardcode to only provide the 'k0' cluster) but that can be fixed later.
The Ceph machinery is a good example of how that can be done.

The new NixOS configs are zero-diff against prod. While this is done
mostly by keeping the logic, we had to keep a few newly discovered
'bugs' around by adding some temporary options which keeps things as they
are. These will be removed in a future CL, then introducing a diff (but
no functional changes, hopefully).

We also remove the nix eval from clustercfg as it was not used anymore
(basically since we refactored certs at some point).
