> *UPD*: After some investigation, I would suggest to rewrite this test, so we
> don't use mocks of metastorage and don't block some metastorage updates and
> wait for further metastorage intereactions, like catalog updates. As an idea,
> we could use {{org.apache.ignite.internal.test.WatchListenerInhibitor}} to
> block reaction on changing of
> {{org.apache.ignite.internal.distributionzones.DistributionZonesUtil#zonesLogicalTopologyKey}}
> so that means that we can skip data nodes update as we wanted in the test
