cluster: k0: move cockroachdb away from bc01n01, fixup joins

Reminded by a power failure on bc01n0{1,2}, we migrate away from at
least one of them into another server.

We also fix up the startup join parameter to not include the node itself
(which is not necessary, but a nice thing to have nonetheless).

Since bc01n01 was the initial node of the cluster, we also disable the
init job for k0 (which we don't care about anyway).
