Support per-test-environment ginkgo flags for node e2e tests to facilitate skipping miss behaving tests in PR builder
We had an issue today where some node e2e tests were timing out in the pr builder. We want to be able to skip tests in the pr builder and leave them running in the CI if this happens again.

Make Privileged pods node e2e use the framework
Made the test more readable along the way with more logs. This should help us triage failures/flakes in the future.

Use pause image depending on the server's platform when testing
Removed all pause image constant strings, now the pause image is chosen by arch. Part of the effort of making e2e arch-agnostic.
The pause image name and version is also now only in two places, and it's documented to bump both
Also removed "amd64" constants in the code. Such constants should be replaced by `runtime.GOARCH` or by looking up the server platform
Fixes: #22876 and #15140
Makes it easier for: #25730
Related: #17981
This is for `v1.3`

- Add junit test reported
- Write etcd.log, kubelet.log and kube-apiserver.log to files instead of stdout
- Scp artifacts to the jenkins WORKSPACE
Fixes#25966

kubelet/cadvisor: Refactor cadvisor disk stat/usage interfaces.
basically
1) cadvisor struct will know what runtime the kubelet is, passed in via additional argument to New()
2) rename cadvisor wrapper function to DockerImagesFsInfo() to ImagesFsInfo() and have linux implementation choose a label based on the runtime inside the cadvisor struct
2a) mock/fake/unsupported modified to take the same additional argument in New()
3) kubelet's wrapper for the cadvisor wrapper is renamed in parallel
4) make all tests use new interface

Add a timeout to the node e2e Ginkgo test runner
Also add a few debugging statements to indicate progress.
Should help prevent #25639, since we'll timeout tests before Jenkins times out the build.

Reimplement 'pause' in C - smaller footprint all around
Statically links against musl. Size of amd64 binary is 3560 bytes.
I couldn't test the arm binary since I have no hardware to test it on, though I assume we want it to work on a raspberry pi.
This PR also adds the gcc5/musl cross compiling image used to build the binaries.

Correct the display of the output when e.g. starting the kubelet fails in the node e2e tests. This
change makes it display a string instead of an array of decimal values.

Framework support for node e2e.
This should let us port existing e2e tests to the node e2e suite, if the tests are node specific.
- Add keep-alive to ssh connection
- Don't try to stop services on image-based runs
- Increase jenkins ci timeout to 90 minutes to accomadate unpredictable go build times
- Remove spammy log statement

Fix PullImage and add corresponding node e2e test
Fixes#24101. This is a bug introduced by #23506, since ref #23563.
The root cause of #24101 is described [here](https://github.com/kubernetes/kubernetes/issues/24101#issuecomment-208547623).
This PR
1) Fixes#24101 by decoding the messages returned during pulling image, and return error if any of the messages contains error.
2) Add the node e2e test to detect this kind of failure.
3) Get present check out of `ConformanceImage.Remove()` and `ConformanceImage.Pull()`. Because sometimes we may expect error to occur in `PullImage()` and `RemoveImage()`, but even that doesn't happen, the `Present()` check will still return error and let the test pass.

Also /cc @resouer, because he is doing the image related functions refactoring.

e2e_node: port privileged pod tests from test/e2e/priviliged.go
The ported test is functionally the same as the original test.
The main difference between the two tests is that the original test relies on
`kubectl` to exec into the container, while the latter directly uses the REST
client of the apiserver. This avoids the need to copy kubectl to the node under
test.

Do not throw creation errors for containers that fail immediately after being started
Fixes (hopefully) #23607
