Redesign integration testing to copy images to nested containers
Previously, the strategy for avoiding lots of rebuilding and repulling for each Docker version being tested was to use a mountpoint to persist /var/lib/docker. This was pretty broken, and may not be a reliable strategy. This commit changes the scripts to instead build/pull images outside the innermost container, and copy them to the final test environment with docker save/docker load. This requires a fair amount of changes, since run.sh must now communicate with the Docker engine that was formerly started by test_runner.sh. The code that starts this engine has been broken out to run_engine.sh so that starting the engine and running the tests under it can be done separately (with the images loaded in between these steps).
