The current interface is kind of clunky and not super easy to use, since
you have to specify parameters to specify which versions to diff. Also
the default isn't the most useful setting.
Change the interface by removing all the parameters and force only one
useful use-case, that is: diffing what's currently live against
what would be live if applied.
The EtcdMain function in integration tests is designed to launch an etcd
instance only when running in a bazel test. For non-bazel, we rely on
hack/make-rules/test-integration.sh to bring up the etcd instance.
This patch fixes the following in EtcdMain:
1. If etcd is not found in ${RUNFILES_DIR} then look in ${PATH}.
2. Try to connect to the etcd started by `make test-integraion`; if it
is up, then don't start etcd.
3. Gracefully shut down etcd after tests.
4. Get a port from the OS instead of deriving it from argv[0].
5. Don't use sync.Once.
The benefit of this change is that integration tests work with `go test`
as well as `make test-integration` without users needing to do anything
special. That makes it much easier to pass go testing flags to tests and
integrate with IDEs.

Initial node performance testing framework.
This PR adds a framework for node performance testing.
Partially fixes: https://github.com/kubernetes/kubernetes/issues/65249.
Use the following command to run this test:
```sh
make test-e2e-node FOCUS="Node Performance Testing" SKIP="" PARALLELISM=1
```
It has been tested in the following environment:
- n1-standard-16
- Ubuntu 16.04
- docker 17.03.2
Note to reviewers:
This PR won't pass node e2e since the docker images in https://github.com/kubernetes/kubernetes/pull/65251 are required for this to function. The node e2e will fail when trying to pull the required images for testing.

CSI Node info registration in kubelet
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:
Fixes#67683
**Special notes for your reviewer**:
Feature issue: https://github.com/kubernetes/features/issues/557
Design doc: https://github.com/kubernetes/community/pull/2034
Missing pieces:
* CSI client retry and exponential backoff logic.
* CSINodeInfo object validation
* e2e test with all the CSI machinery.
An RBAC rule is also added to support external-provisioner topology updates.
**Release note**:
```release-note
Registers volume topology information reported by a node-level Container Storage Interface (CSI) driver. This enables Kubernetes support of CSI topology mechanisms.
```
