e2e_node: lower the log verbosity level
The current level is so high that the logs are almost unreadable.
This fixes#27593
[k8s.io] Kubelet metrics api when querying /stats/summary [It] it should report resource usage through the stats api
And the logs show following error:
Jun 21 15:57:13 localhost journal: tee: /test-empty-dir-mnt: Is a directory

Add image pulling node e2e
Fixes#27007.
Based on #27309, will rebase after #27309 gets merged.
This PR added all tests mentioned in #27007:
* Pull an image from invalid registry;
* Pull an invalid image from gcr;
* Pull an image from gcr;
* Pull an image from docker hub;
* Pull an image needs auth with/without secrets.
For the imagePullSecrets test, I created a new gcloud project "authenticated-image-pulling", and the service account in the code only has "Storage Object Viewer" permission.

Fix node e2e coreos kubelet cgroup detection
Fixes#26979#26431
The root issue, as best I can tell, is that cgroup detection does not work when the kubelet is started under an ssh session and the systemd `*Accounting` variables are set. I added additional logging and noted some differences in the cgroup slice names between those cadvisor returns and the kubelet detects for itself.
This difference does not occur if the kubelet is properly running under a unit. That environment is also a more common and sane environment.

Port the downward api test to the node e2e suite
Also extend the framework to allow a custom client config loading function, so
that the node e2e suite can reuse the same framework across tests.
This fixes#26609
/cc @timstclair @pwittrock
This reverts commit 2494c77972.
The previous commit, which launches the kubelet under `systemd-run`,
fixes an error in detecting the kubelet's cgroup stats.
Fixes#26979
Also includes other improvements:
- Makefile rule to run tests against remote instance using existing host or image
- Makefile will reuse an instance created from an image if it was not torn down
- Runner starts gce instances in parallel with building source
- Runner uses instance ip instead of hostname so that it doesn't need to resolve
- Runner supports cleaning up files and processes on an instance without stopping / deleting it
- Runner runs tests using `ginkgo` binary to support running tests in parallel

Mark runtime conformance tests as flaky and not run them in jenkins CI.
For #26809
@pwittrock As discussed offline, marking runtime tests as flaky for now. I'm not sure if those tests are required. Testing docker in every Kubernetes PR is un-necessary.
These tests can be run periodically in a separate CI. AFAIK, these tests don't seem to exercise any kube features.

Updated the e2e setup.sh script to enable cpu and memory accounting.

- Exit non-0 if infrastructure failures happen
- Exit 0 if no infrastructure failures happen regardless of test results
(Jenkins will use junit.xml to determine test results)

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.
#24577

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

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

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
