Issue	Description
#3110546	Allow contributed modules (mostly database drivers) to override tests in core

Known issues

• mysqli::rollback() returns TRUE if there's no active transaction. This is diverging from PDO MySql. TransactionTest::testTransactionWithDdlStatement() fails for this reason. A PHP bug report exists, https://bugs.php.net/bug.php?id=81533.
• Apparently, mysqli::rollback(0, 'savepoint-1') does not respect the savepoint passed in, and rolls back the entire transaction. I had to revert to using mysqli::query('ROLLBACK TO SAVEPOINT savepoint-1') to get transaction tests pass. Could not find reported bugs for this.
