deployer not deploying and yet exiting with 0

Created by: knightsamar

As seen in [1] the deploy_wrapper and deploy.sh scripts were not successful in deploying the images but still exited with 0 and hence the taster phase was initiated.

Thus, we have two problems at hand:

1. deploy phase is not able to find the files at the right place.
2. deploy phase is not exiting with the actual exit status of the openstack command called for deploying the image (or setting the name).
