Add cancelTimeout to cancel the query timeout

[AfsanehR-zz]

Added new connection property of cancelQueryTimeout. This will address issue #525 where querytimeout hangs and does not throw exception due to silent dropping of connection.
The driver will wait the total amount of cancelQueryTimeout + queryTimeout to drop the connection and close the channel.

Note: The new connection property of cancelQueryTimeout will be effective only if the queryTimeout is set in the driver.
