          Issue Type: Task
          Components: sql
            Reporter: Igor Seliverstov


We need to change:
 * rows with the same key and different versions should be placed in a tree ordered by version decending
 * move next version from BTree leafs to data rows
 * filters according to next logic: the row is visible if leaf version is less than assigned and not active and max_version of referenced row is NA or heigher than assigned or active
