This Feature allow to greatly reduce the size of the docker images generated with mutlistage build. This is very efficient for source build images (debian ones).
So if you have an older version of Docker can you still use these from AnsibleCheck/..., just confirming that we won't break existing travis implementations depending on it.

Thanks docker (https://docs.docker.com/engine/userguide/eng-image/multistage-build/)
PS: need docker-ce >= 17.06, so I've update it in .travis.yml to make tests OK.
