Fixes for running the master branch on the UTH nodes

Just tried to run the master branch on our nodes (deployed with the standard cloud images)

Some fixes to get it running (seems that some directories regarding OAI have been renamed)

For the deployment, ran0 and eth1 interfaces must be present on the workers, maybe we need to clarify this on the README as well
