Enable split logging for cinder-novaclient interaction

This patch ensures that log messages[1][2][3] are logged only when
keystoneauth=DEBUG is enabled in cinder.conf. This will also enable
us to consume split_logger config option [4] when enabled in cinder
without making any additional changes in client code.
