tripleo-common/scripts/upgrade-non-controller.sh
marios 9278442537 Adds basic logging to the upgrade-non-controller.sh utility
We are using this to upgrade those roles that have the
disable_upgrade_deployment flag set to true. This adds some basic
logging - logfiles generated in the working directory by name/uuid
