Update misc to reflect last API changes

The docker API changed lately, making our tests failing for no reason.
see https://github.com/dotcloud/docker/pull/3119 for more info.

This commit is raising the question of using a package manager for this project. This is the second time since I started to work on it that tests are failing because of API changes.
This has been discussed thousand of time (at least) on go-nuts, and the answer was often "an API should not change, otherwise it's a different branch or project". In the real life, we can see API changes over time (breaking the "open/close" rule), and will continue. I'm available to discuss possibilities here, but I _really_ think we have to do something.
Thanks
