Currently the rkt driver does not expose a DriverNetwork instance after starting the container, which means that address_mode = 'driver' does not work. To get the container network information, we can call `rkt status` on the UUID of the container and grab the container IP from there. For the port map, we need to grab the pod manifest as it will tell us which ports the container exposes. We then cross-reference the configured port name with the container port names, and use that to create a correct port mapping. To avoid doing a (bad) reimplementation of the appc schema(which rkt uses for its manifest) and rkt apis, we pull those in as vendored dependencies. The versions used are the same ones that rkt use in their glide dependency configuration for version 1.28.0.
