Docker should use systemd drop-in for proxy variables

[Kevin Lefevre]

Docker should use systemd drop-in units for settings proxy configuration :

https://docs.docker.com/engine/admin/systemd/#/http-proxy

I already submitted a pacth for swarm : https://bugs.launchpad.net/magnum/+bug/1632698

This is the same patch for Kubernetes on CoreOS and Atomic template

    Fix no_proxy evaluation for Swarm clusters

    At the moment, no_proxy variable is evaluated separately for docker
    daemon and for swarm-manager container running in docker. Evaluated
    value for swarm-manager is not getting into cloud-init script, because
    $NODE_PROXY token is getting replaced by Heat str_replace function.
    This commit is intended to unify NO_PROXY evaluation and also fix the
    issue with swarm-manager.
