- Move from the old github.com/golang/glog to k8s.io/klog
- klog as explicit InitFlags() so we add them as necessary
- we update the other repositories that we vendor that made a similar
change from glog to klog
* github.com/kubernetes/repo-infra
* k8s.io/gengo/
* k8s.io/kube-openapi/
* github.com/google/cadvisor
- Entirely remove all references to glog
- Fix some tests by explicit InitFlags in their init() methods

Not all users of the E2E framework want to run cloud-provider specific
tests. By splitting out the code it becomes possible to decide in
a E2E test suite which providers are supported.
This is achieved in two ways:
- the framework calls certain functions through a provider
interface instead of calling specific cloud provider functions
directly
- tests that are cloud-provider specific directly import the
new provider packages
The ingress test utilities are only needed by a few tests. Splitting
them out into a separate package makes the framework simpler for test
suites not using those tests.
Fixes: #66649
This change allows validators to pass warnings as well as errors. This
was needed because of how support for docker 1.13+ and the new EE and CE
versions is currently being handled.
This commit wires-in the pre-existing `--container-runtime` flag for
local node_e2e testing.
This is needed in order to further skip docker specific testing
and validation.
Local CRI node_e2e can now be performed via
`make test-e2e-node RUNTIME=remote REMOTE=false`
which will also take care of passing the appropriate arguments to
the kubelet.

Rename "release_1_5" clientset to just "clientset"
We used to keep multiple releases in the main repo. Now that [client-go](https://github.com/kubernetes/client-go) does the versioning, there is no need to keep releases in the main repo. This PR renames the "release_1_5" clientset to just "clientset", clientset development will be done in this directory.

Node Conformance Test: Containerize the node e2e test
For #30122, #30174.
Based on #32427, #32454.
**Please only review the last 3 commits.**
This PR packages the node e2e test into a docker image:
- 1st commit: Add `NodeConformance` flag in the node e2e framework to avoid starting kubelet and collecting system logs. We do this because:
- There are all kinds of ways to manage kubelet and system logs, for different situation we need to mount different things into the container, run different commands. It is hard and unnecessary to handle the complexity inside the test suite.
- 2nd commit: Remove all `sudo` in the test container. We do this because:
- In most container, there is no `sudo` command, and there is no need to use `sudo` inside the container.
- It introduces some complexity to use `sudo` inside the test. (https://github.com/kubernetes/kubernetes/issues/29211, https://github.com/kubernetes/kubernetes/issues/26748) In fact we just need to run the test suite with `sudo`.
- 3rd commit: Package the test into a docker container with corresponding `Makefile` and `Dockerfile`. We also added a `run_test.sh` script to start kubelet and run the test container. The script is only for demonstration purpose and we'll also use the script in our node e2e framework. In the future, we should update the script to start kubelet in production way (maybe with `systemd` or `supervisord`).

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:
```

Use report-dir in test framework instead.
We already have `report-dir` option in framework test context.
The node e2e framework should use it as well.

Node E2E: Move the node name initialization to first function of SynchronizedBeforeEach
Currently, we start e2e services in the first function of `SynchronizedBeforeEach` to make sure that we only start them once even we are running test in parallel test nodes.
However, e2e services require `NodeName`, but we initialize `NodeName` in the second function.
This PR moved the initialization logic into the first function, and shared the node name with all test nodes via the `SharedContext`.
