Add twining technique to replacement_sdts in Control Snapshots

[bschlottfeldt]

Could be an option for the value in replacement_sdts to take the closest active snapshot existent in the table, so if a snapshot is not active the replacement_sdts will take the timestamp value from the closest active one.
Idea came from @marcfinger and its based on the technique shown here:
