> In distribution zone manager we have several local entities that hold some states. 
> * DistributionZoneManager.ZoneState#topologyAugmentationMap 
> * DistributionZoneManager#nodesAttributes
> Currently {{DistributionZoneManager.ZoneState#topologyAugmentationMap}} is being cleaned only on a node, that successfully writes data nodes, which seems to be incorrect, because for example a node, that never writes data nodes, will never clean up its state.
> Need to find a proper solution for states utilisation.
> UPD:
> Proposed solution:
> ZoneState#topologyAugmentationMap should be cleared when we read scaleUp/Down keys in saveDataNodesToMetaStorageOnScaleUp/Down methods, 
> when we retrieved this keys, it is safe to call {{zoneState.cleanUp(Math.min(scaleDownTriggerRevision, scaleUpTriggerRevision))}}, but we also need to change semantic of {{cleanUp}} method, so we need to call {{topologyAugmentationMap.headMap(toKey, false).clear()}} with false flag, to not include the passed key and not to remove it from the tree.
