> In https://issues.apache.org/jira/browse/IGNITE-19061 we have provided design for a correct restart of a node and recovering all Distributed Zones states. 
> In this ticket we want to restore {{DistributionZoneManager#nodesAttributes}}, check that {{DistributionZoneManager#logicalTopology}} is restored correctly. To achieve restoring {{DistributionZoneManager#nodesAttributes}}, we need to save it synchronously to Vault when we handle {{DistributionZoneManager#createMetastorageTopologyListener}}, and read this value on a restart in {{DistributionZoneManager#start}}
> Details could be found in the design document.
> As a result, this global states must be restored to the state that they had before restart. Test for restart scenarios must be provided, so we want to test, that any restart of a node leads to correct global states restoring, meaning that their state before restart are restored.
