[Docker] Deploy to Docker container
Port the implementation of Docker containers.
Docker container will be a namespace that contains one or more process nodes.
Ideally the IR implementation will be a simpler version of the goproc namespace implementation. The main concerns will be collecting and packaging artifacts from the contained processes, including software dependencies like installing Go; getting the cmd line instantiation strings; and ensuring that argnodes are passed from outside the container to the processes, presumably through environment variables.
