Node E2E: Remove fatal error in e2e_node_suite_test.go
Addresses https://github.com/kubernetes/kubernetes/issues/30779#issuecomment-240532190.
Currently we run node e2e test in parallel, and ginkgo makes sure that we only initialize test framework in the first test node.
However, because we throw out some fatal error during the initialization. Once there is an fatal error, the first test node will die immediately without reporting any error, and the other nodes will exit because the first node is gone with meaningless error.
If kubelet start fails, we'll get something like:
```

Add benchmark to jenkins
This PR contains the following changes:
1. Add more tests in density benchmark test;
2. Add the peak value (100%) in latency and CPU usage statistic data;
3. Move the Ginkgo focus flag from e2e_remote.go to run_e2e.go;
4. Support running benchmark in run_e2e.go. The benchmark configuration file is an extension of image configuration. Each item requires additional GCE machine type (e.g. n1-standard-1, default value will be used if empty) and test names (Ginkgo focus regex strings). A test item is regarded as benchmark if the tests field is non-empty.

Node Conformance Test: Statically link apiserver
For #30122, #30174.
Based on #30116, #30198, #30200.
**Please only review the 4th PR.**
This PR is part of our roadmap to package node conformance test.
The 1st commit is from #30116, which started e2e services in a separate process.
The 2nd commit is from #30198, it statically linked etcd into the node e2e framework.
The 3rd commit is from #30200, it moved namespace controller into e2e services.
The 4th commit is new, it statically linked apiserver into the node e2e framework.

In order to allow forward progress on this feature, it takes the commits from #28017#29049 and then it globally disables the flag that allows these features to be exercised in the kubelet. The flag can be re-added to the kubelet when its actually ready.

OpenAPI / Swagger2 spec generation
This is alpha version of OpenAPI spec generation. Generated "/swagger.json" file (accessible on api server) is a valid OpenAPI spec with some warnings that will be fixed in next versions of spec generation. Currently it is possible to generate a client using this spec though I did not test the clients.
reference: #13414
**Release note**:
```release-note
Alpha support for OpenAPI (aka. Swagger 2.0) specification serves on /swagger.json

Node E2E: Make readiness check handling process exits with 0 exit code.
As is mentioned by @mtaufen:
"there is a problem with the way service `start` is currently implemented in test/e2e_node/e2e_service.go. If the Kubelet exits with status 0 before the health check completes, cmdErrorChan will be closed and, as a result, nil will be read from that channel, and you will return a nil error from `start`."
This PR changes the logic to:
1) If the err channel returns an error, return the error
2) If the err channel returns a nil, ignore it and continue checking readiness.
3) If the err channel is closed before readiness check succeeds, replace it with `blockCh` and continue checking readiness.

Move UTs that block on apiserver to integration tests.
In validating etcd.v3client we had uncovered that a change in the behavior of the client https://github.com/coreos/etcd/issues/6162 , caused a number of unit tests to fail. These test failures were due to the fact that the unit tests were trying to standup a apiserver even though there was no etcd backend stood up.
This PR simply shuffles those tests to integration tests, which is where they should be.
