> NullPointerException in log on start the first node in the cluster if DistributionZoneConfigurationSchema#dataNodesAutoAdjustScaleUp and DistributionZoneConfigurationSchema#dataNodesAutoAdjustScaleDown are 0.
> How to reproduce:
> # Set DistributionZoneConfigurationSchema#dataNodesAutoAdjustScaleUp = 0 and DistributionZoneConfigurationSchema#dataNodesAutoAdjustScaleDown = 0.
> # Start the test which starts the node. For example ItTablesApiTest#testAddIndex.
> # See NullPointerException in the log.

> Caused by: java.lang.NullPointerException at java.base/java.io.ByteArrayInputStream.<init>(ByteArrayInputStream.java:108) at org.apache.ignite.internal.util.ByteUtils.fromBytes(ByteUtils.java:152) at org.apache.ignite.internal.distributionzones.DistributionZoneManager.lambda$saveDataNodesToMetaStorageOnScaleUp$32(DistributionZoneManager.java:1096) at org.apache.ignite.internal.util.IgniteUtils.inBusyLock(IgniteUtils.java:870) at org.apache.ignite.internal.distributionzones.DistributionZoneManager.lambda$saveDataNodesToMetaStorageOnScaleUp$33(DistributionZoneManager.java:1090) at java.base/java.util.concurrent.CompletableFuture$UniCompose.tryFire(CompletableFuture.java:1072) ... 13 more {code}
> The root cause is zoneDataNodesKey, zoneScaleUpChangeTriggerKey, zoneScaleDownChangeTriggerKey of zones are not initialized on node start if vaultMgr.get(zonesLogicalTopologyKey()) is null.
> *Definition of Done*
> zoneDataNodesKey, zoneScaleUpChangeTriggerKey, zoneScaleDownChangeTriggerKey are initialized on the node start.
