Move ResourceQuantities from reddwarf-scheduler to reddwarf-core so both
scheduler and runtime share K8s CPU/memory parsing. Add cpu_as_zone_cap()
and memory_as_zone_cap() conversions for illumos zonecfg format. Wire
pod_to_zone_config() to aggregate container limits (with requests fallback)
and pass capped-cpu/capped-memory to the zone, closing the resource pipeline.
