Add density (batch pods creation latency and resource) and resource performance tests to `test-e2e-node'
This PR contains two new tests (migrate from e2e test):
1. Density test: verify startup latency and resource usage when create a batch of pod with throughput control. Throughput control is done by sleep for an interval between firing concurrently create pod operations.
It tests both batch creation and sequential (back-to-back) creation and report the throughputs.
2. Verify resource usage of steady state kubelet.
The test creates a new resource controller for `test-node-e2e' (resource_controller.go) which monitors resource through a standalone Cadvisor pod (port 8090) with 1s housekeeping interval.

Fix an issue where cadvisor was unable to report container filesystem stats for LVM-based
devicemapper thin pools.
Fix an issue where cadvisor would not report any stats for a container if it failed to get the
filesystem stats when Docker's storage driver is devicemapper.

This commit updates all of them and updates the central LICENSE file.
Add it as a special case package root and import the license file. This was
the only UNKNOWN license, prior to the change to not look at upstream repo
state.
This code used to actually reach out to the internet to look for files. This
is flaky, slow, and semantically WRONG. The license that is upstream might
actually be different than what we have vendored. Only look at local files.
This now passes back-to-back updates and verifies.

Docker has removed the ParseRepositoryTag() function in
leading to failures using the kubernetes Go client API.
Lets use github.com/docker/distribution reference.ParseNamed()
instead.
Failure:

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.
