Add a database key `bundle` that contains a path to a Docker dev bundle eg `/.../docker/bundles/1.13.0-dev` where the docker binaries to run can be found. This will be paired with a script in `docker/docker` to set this key, so users can easily help contribute to Docker development. The change will be permanent until the key is removed or a factory reset is done, or the bundle cannot be found. Signed-off-by: Justin Cormack <justin.cormack@docker.com>
