> CORE_IDX and FREEDISK ConditionType reuse this metric name, but they assume the values are expressed in gigabytes. This alone is confusing considering the name of the metric.
> Additionally, it causes conflicts in the simulation framework that would require substantial changes to resolve (ReplicaInfo-s in SimClusterStateProvider keep metric values in their variables, expressed in original units - but then the Policy assumes it can put the values expressed in GB under the same key... hilarity ensues).
