This makes two changes to the zuul-launcher log config: * It routes the root logger to the log files as well. This way, if there are any un-specifified log entries at WARNING or above, they will go to the files we actually look at, as well as the console. * It suppresses paramiko.transport messages. This module frequently logs at ERROR level, every time we receive an incompatible ssh host key (which is often). Get rid of those messages. All other paramiko messages will be handled by the root logger at WARNING level, which is what this was doing before. Change-Id: Ie58fc995c40774285b4a2101aa7ff18ea0d70171
