AWS new resource identifiers
We use currently for our tests the old (short) identifier. In July 2018, we'll have to use the new longer ones.
https://eu-central-1.console.aws.amazon.com/ec2/v2/home?region=eu-central-1#IdFormatSettings: "default_image": "ami-2a34e94a", provider/cloud.json.template
We might need to change somethings when broken, or before.
