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).

- Add a command line argument to run_multiversion.sh which has it start
a docker daemon. This allows it to run directly inside an outermost
docker-integration container instead of running outside all containers.
- Install Docker 1.7.1 intead of 1.7.0-rc1 in the docker-integration
container. 1.7.0 has a bug that prevents "docker cp" from working
properly.

This is much better than downloading the builds with curl, because
Docker is intelligent about only pulling what it needs.
We use tagged versions of dind for the released version, and dind-master
for a master build.

Add a run_multiversion.sh script that downloads a variety of Docker
engines and runs the integration tests against each of them.
Skip some of the tests when running with Docker 1.6.0. It has a bug that
prevents these tests from completing successfully.
