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.
