We need to add a new method to QueryProcessor that will be responsible for processing multistatements query.

// TBD suggested method signature

In general, statements must be executed one by one in the order they are specified in the script.

// TBD suggested for parsing

Due to the lazy nature of SQL engine, the moment when the current statement is "complete" depends on the user who drains the cursor.
To avoid dependency on a user's actions, it proposed to consider statement being "complete" as soon as first page is ready to be returned to the user.

// TBD reference to ticket about SqlCursor event
