Skeleton crew

The off-hours pattern of scaling a service down to a single replica (not zero) to keep it warm and reachable at minimal cost. A single replica does NOT preserve quorum: quorum systems (etcd, ZooKeeper, HA databases) need a majority of an odd-numbered set, so skeleton crew suits stateless or non-quorum workloads, not quorum-dependent ones.
