so-ad7: build per-pod Service for maintenance container 

get_services() now also includes the container named by
maintenance-service: in its container_ports map, so the
maintenance pod's {app_name}-{pod_name}-service gets created
permanently. _restart_with_maintenance can then swap Ingress
backends to a real Service that has Endpoints.

The Service is only externally reachable during the Ingress swap
window; outside of that, no Ingress rule routes to it, so it sits
idle as a warm standby (matching the maintenance pod itself).
