> Extend test coverage for WatchListener in DistributionZoneManager

> Key: IGNITE-18564

> h3. Motivation
> DistributionZoneManagerWatchListenerTest checks only default zone. Now when
> individual zone change trigger were created it is possible to test custom
> zones too. So need to add a custom zone to all tests in
> DistributionZoneManagerWatchListenerTest.
> DistributionZoneManager has a watch listener which is triggered on update
> "distributionZones.logicalTopology" key and updates zone dataNodes in the
> metastorage. Also DistributionZoneManager has a method
> initDataNodesFromVaultManager() which save zone dataNodes on
> DistributionZoneManager#start(). DistributionZoneManagerWatchListenerTest
> checks this logic. But it checks only for default zone. Now when individual
> zone change trigger keys were created it is possible to test custom zones
> too. So need to add a custom zone to all tests in
> DistributionZoneManagerWatchListenerTest.
> # testDataNodesOfDefaultZoneUpdatedOnWatchListenerEvent - the test checks
> that dataNodes is updated on watch event. Need to add custom zone and check
> it.
> # testStaleWatchEvent - the test checks that dataNodes is not updated on
> stale watch event. Need to add custom zone and check it.
> # testStaleVaultRevisionOnZoneManagerStart - the test checks that dataNodes
> is not updated from the vault on DistributionZoneManager#start() if the vault
> applied revision is stale. Need to add custom zone and check it.
> # testDataNodesUpdatedOnZoneManagerStart - the test checks that dataNodes is
> updated from the vault on DistributionZoneManager#start(). Need to add custom
> zone and check it.
> # testLogicalTopologyIsNullOnZoneManagerStart - the test checks that
> dataNodes is not updated from the vault on DistributionZoneManager#start() if
> "distributionZones.logicalTopology" is null in the vault. Need to add custom
> zone and check it.
> *Definition of Done*
> Tests in the DistributionZoneManagerWatchListenerTest check not only default
> zone, but also a custom zone.
