Improve code when setting query timeout. It used to call the sys.settimeout(bigint) which is deprecated as of release Jun2020 (11.37.7) and replaced by new sys.setquerytimeout(int). As the server call was done from two places MonetConnection.isValid() and MonetStatement.internalExecute(), I created a single utlity method which is now called instead.
