It would be helpful when the thread name has a meaningful name. We could achieve this by using a ThreadFactory as second argument to set the name a new thread is created.

This change implements `Statement#setQueryTimeout()` method. It is implemented by scheduling a background task and calling `Statement#cancel()` when timeout expires. Timeouted statement has the same behaviour as it would be if cancelled manually - `SQLException` is thrown and the statement is closed. Timeout is applied for all `execute*` calls. For `executeBatch()` it is applied separately for every single query in a batch. Testing: new test added. Fixes: duckdb#212

The implementation of `Statement#setQueryTimeout()` added in duckdb#247 uses a background thread to perform the query cancellation on timeout. Because that thread is not marked as "daemon" one, it can prevent JVM shutdown. This change makes the scheduler thread "daemon" and additionally exposes `DuckDBDriver#shutdownQueryCancelScheduler()` method that allows to shut down the scheduler manually. Testing: manual test added that checks that queries with timeout set can be executed (with timeout ineffective) after the scheduler is shut down. Fixes: duckdb#504
