Update the docker client related vendor pkg to newer version.

Existing go-dockerclient pkg does not support latest docker API,
e.g., Docker 1.12. This patch will update docker client pkg to
latest version, and update related dependencies, including:

* some sub pkgs of github.com/docker/docker
* github.com/docker/engine-api/types/filters
* github.com/docker/engine-api/types/versions
* github.com/fsouza/go-dockerclient
* github.com/docker/go-units
* github.com/hashicorp/go-cleanhttp
* github.com/opencontainers/runc
* github.com/Sirupsen/logrus

On the other hand, to meet the usage of go vendor, move docker
client dependent pkgs to outside for easier further updating.

This patch also fix #2044 when using the Docker 1.12 client.
