Description

Savepoint provides handle for user app to partially rollback a transaction to the specific point.

Need to add support for next commands:
"Savepoint" - creates save point with specific identificator (name, label or smth like this)

"Rollback to savepoint" - rollback transaction to savepoint.

"Release savepoint" - destroy previously created savepoint.
