Includes the changes from #80922 (that were reverted), and updates the test to appropriately add intolerable taints to all nodes except the target node
Originally, printOnce() was implemented for printing debugging message
once for checking actual value is the same as expected value.
However even if an error doesn't happen in ExpectEqual(), printOnce()
is called internally. Then the second ExpectEqual() doesn't output
the debugging message if an error happens. This makes debugging
difficult, let's just remove it for debugging.
A number of tests rely on SSH behavior but are not marked with
SkipUnlessSSHKeysPresent(). This means that the tests will run and
hang. This can be confusing for users because they may not know why
the tests failed. Instead, we should be reporting on the known issue
and skipping the test (hence why the helper Skip... function exists).
The conformance test "validates resource limits of pods that are
allowed to run" is failed if master node doesn't have taints.
The reason is that nodeList which should consist of schedulable
nodes is gotten with GetMasterAndWorkerNodes() and master nodes
were excluded from nodeList.
This makes nodeList be gotten with GetReadySchedulableNodesOrDie()
and nodeList can consist of schedulable nodes.
I think, if a pod doesn't have any tolerations, we don't prefer node without taints to
the one which has taints in https://github.com/kubernetes/kubernetes/blob/master/pkg/scheduler/algorithm/priorities/taint_toleration.go#L29, so there is no point in testing that particular functionality. The side effect of the above is, since we're going round-robin in every scheduling cycle sometimes we're choosing first node and in the next cycle we'd move onto next node(where taints are not being applied), so it's causing problem unnecessarily
"validates resource limits of pods that are allowed to run" test of
conformance tests are flake on some local environments.
The CPU workload pods don't seem work well and nodes have still CPU
capacity after running the workload pods. Then the conformance test
failed unexpectedly.
This adds message which shows how much CPU used by the workload pods
for investigating it easily.
Quite a few images are only used a few times in a few tests. Thus,
the images are being centralized into the agnhost image, reducing
the number of images that have to be pulled and used.
This PR replaces the usage of the following images with agnhost:
- audit-proxy
- crd-conversion-webhook
- entrypoint-tester
- inclusterclient
- iperf
- porter
- serve-hostname
Including the gpu information simplifies driver version verification.
nvidia-smi is used in order to display gpu information, which contains the driver version.
- Add a package "node" under e2e/framework and alias e2enode;
- Rename some functions whose name have redundant string.

This way we can be sure that the kubelet can't communicate with the
master, even if falls-back to the internal/external IP (which seems to
be the case with DNS)
Issue #56787
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.

Remove e2e-image-puller
**What this PR does / why we need it**:
A long time ago, We added the image prepulling as a workaround due to
the overwhelming amount of flake caused by pulling during the tests.
This functionality has been broken for a while now when we switched to a
COS image where mounting `docker` binary into `busybox` stopped working.
So we just have dead code we should clean up.
