> 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.
