Kubelet: Start using the official docker engine-api

For #23563.

This is the **first step** in the roadmap of switching to docker [engine-api](https://github.com/docker/engine-api).
In this PR, I keep the old `DockerInterface` and implement it with the new engine-api.
With this approach, we could switch to engine-api with minimum change, so that we could:
* Test the engine-api without huge refactoring.
* Send following PRs to refactor functions in `DockerInterface` separately so as to avoid a huge change in one PR.

I've tested this PR locally, it passed all the node conformance test:
```
make test_e2e_node

Ran 19 of 19 Specs in 823.395 seconds
SUCCESS! -- 19 Passed | 0 Failed | 0 Pending | 0 Skipped PASS

Ginkgo ran 1 suite in 13m49.429979585s
Test Suite Passed
```
And it also passed the jenkins gce e2e test:
```
go run hack/e2e.go -test -v --test_args="--ginkgo.skip=\[Slow\]|\[Serial\]|\[Disruptive\]|\[Flaky\]|\[Feature:.+\]"

Ran 161 of 268 Specs in 4570.214 seconds
SUCCESS! -- 161 Passed | 0 Failed | 0 Pending | 107 Skipped PASS

Ginkgo ran 1 suite in 1h16m16.325934558s
Test Suite Passed
2016/03/25 15:12:42 e2e.go:196: Step 'Ginkgo tests' finished in 1h16m18.918754301s
```

I'm writing the design document, and will post the switching roadmap in an umbrella issue soon.

# go-winio
This repository contains utilities for efficiently performing Win32 IO operations in
Go. Currently, this is focused on accessing named pipes and other file handles, and
for using named pipes as a net transport.
This code relies on IO completion ports to avoid blocking IO on system threads, allowing Go
to reuse the thread to schedule another goroutine. This limits support to Windows Vista and
newer operating systems. This is similar to the implementation of network sockets in Go's net
package.
Please see the LICENSE file for licensing information.
Thanks to natefinch for the inspiration for this library. See https://github.com/natefinch/npipe
for another named pipe implementation.
