Issue MESOS-4499: Docker provisioner store should reuse existing layers in the cache.
Currently, the docker provisioner store will download all the layers associated with an image if the image is not found locally, even though some layers of it might already exist in the cache. This is problematic because anytime a user deploys a new image, Mesos will fetch all layers of that new image, even though most of the layers are already cached locally.
