Set "VolumesFrom" when starting containers

This is necessary when working with Docker 0.10.0 and up. Fortunately,
we can set it both when creating and starting, and retain compatibility
with 0.8.x and 0.9.x.

recreate_containers() is now responsible for starting containers, as
well as creating them. This greatly simplifies usage of the Service
class.
