prepare-docker-dind: make docker start optional

This change makes it possible to disable docker start after
prepare-docker-dind role executes.
Needed for docker role that wants to start docker by itself.
Note that the docker role also tries to install docker by itself, and
prepare-docker-dind does the same.
The reason is that it makes it possible to fix the version of installed docker.
