rkt fetch does not work behind proxy

[Kevin Lefevre]

On CoreOS, everything is containerized, Etcd, Hyperkube, Flannel. Core system services runs with rkt.

When using magnum behind proxy, we are only setting up docker configurtion but rkt is not using the proxy so it is not working and fails to fetch images.

We add proxy to /etc/environment also so I think we should add /etc/envionment inside the systemd unit file.

Along with intregrating this patch https://review.openstack.org/#/c/457806/ for ecrty driver we should be set for using magnum behind corporate http proxy.
