This finishes the regeneration of all cluster CAs/certs to be never
expiring ED25519 certs.
We still have leftovers of the old Kube CA (and it's still being
accepted in Kubernetes components). Cleaning that up is the next step.

This pretty large change does the following:
- moves nix from bootstrap.hswaw.net to nix/
- changes clustercfg to use cfssl and moves it to cluster/clustercfg
- changes clustercfg to source information about target location of
certs from nix
- changes clustercfg to push nix config
- changes tls certs to have more than one CA
- recalculates all TLS certs
(it keeps the old serviceaccoutns key, otherwise we end up with
invalid serviceaccounts - the cert doesn't match, but who cares,
it's not used anyway)
