> Transaction recovery procedure is initiated when near node failed before 
> transaction was finished.
> In MVCC transactions _partition update counter_ modification is started on 
> prepare phase. If a transaction was prepared at least on one node we need to 
> finish _partition update counter_ modification consistently on all 
> participating nodes.
> Also recovered transaction should be removed from active transactions list on 
> mvcc coordinator.
