Fix spec for addons

For some reasons kubectl apply -f -l doesn't want to spin up
contrail-network-controller.
* This patch corrects metadata for addons so kube-addons.sh can spin
  them up correctly.
* Rename directory from contrail_network_controller to
  contrail-network-controller for unified view
