>  , test failure of 
> {{{}org.apache.ignite.internal.raftsnapshot.ItTableRaftSnapshotsTest: 
> leaderFeedsFollowerWithSnapshot{}}}, we see that there are no log messages on 
> replica about lease negotiation, which means that it didn't even started on 
> the placement driver active actor's side.  But the active actor has started 
> before. Log doesn't provide any information about the detail what happened on 
> LeaseUpdater.
> The suggestion is to add logging to know whether some exception happened in 
> {{{}updateLeaseBatchInternal{}}}, or in {{{}LeaseNegotiator#negotiate{}}}, 
> and logging of lease updating statistics (how many groups without 
> leaseholders were detected, how many negotiations are in progress, how many 
> leases are prolonged).
