Privileged option is part of host config, not config

I tried to create a privileged container with docker-py, but it wasn't working. Turns out privileged is part of host config and should be passed as part of run! https://github.com/dotcloud/docker/blob/master/container.go#L72

Also, take a look at my issue in docker regarding inspecting a container for privileged option: https://github.com/dotcloud/docker/issues/2595
