Enable downloading binaries and containers

The *download_run_once* kubespray config option allows to download
container images only once then push to cluster nodes and the
*download_localhost* option makes the installer node a delegate for
pushing images while running the deployment with ansible.

These two options pretends to reduce the amount of traffic during
the deployment time of the Kubernetes cluster.
