Madhu Venugopal 1ac350a0ec Support for --publish-service flag in docker run
This commit makes use of the CNM model supported by LibNetwork and
provides an ability to let a container to publish a specified service.
Behind the scenes, if a service with the given name doesnt exist, it is
automatically created on appropriate network and attach the container.
