Refactor the Sandbox package into Sandbox + Container.
This is a necessary prerequisite for supporting multiple containers in a single sandbox. All the commands (in cmd package) now call operations on Containers (container package). When a Container first starts, it will create a Sandbox with the same ID. The Sandbox class is now simpler, as it only knows how to create boot/gofer processes, and how to forward commands into the running boot process. There are TODOs sprinkled around for additional support for multiple containers. Most notably, we need to detect when a container is intended to run in an existing sandbox (by reading the metadata), and then have some way to signal to the sandbox to start a new container. Other urpc calls into the sandbox need to pass the container ID, so the sandbox can run the operation on the given container. These are only half-plummed through right now.
