Without this patch, containers inherit the open file descriptors of the daemon, so my "exec 42>&2" allows us to "echo >&42 some nasty error with some bad advice" directly into the daemon log. :)
Also, "hack/dind" was already doing this due to issues caused by the inheritance, so I'm removing that hack too since this patch obsoletes it by generalizing it for all containers.

This also migrates the volumes from integration tests into the new cli
integration test framework.

As explained in https://github.com/dotcloud/docker/issues/4979
--volumes-from fails with ENOFILE errors.
This is because the code tries to look at the "from" volume without
ensuring that it is mounted yet. We fix this by mounting the containers
before stating in it.
Also includes a regression test.
