Similar functionality is required across e2e tests for RuntimeClass.
Let's create runtimeclass as part of the framework/node package.

NodeResourceFit plugin's Filter method responsible for checking if a pod fits
a given node ignores resource limits and acknowledge resource requests only.
Given both tests validating resource limits of pods were setting only pod resource limits,
ability of NodeResourceFit plugin to properly filter nodes was not tested at all.
- Use preemptor pod's Status.NominatedNodeName to signal success of the Preemption behavior
- Optimize the test to eliminate unnecessary Pods creation
- Increase timeout from 1 minute to 2 minutes
This reverts commit 4d3d364d2b.
This commit promoted a test to conformance and also changed the test at
the same time. It should have been split up into two PRs to verify
whether the change had the intended effect. The test is now failing
consistently, so reverting.
This PR moves functions from test/e2e/framework.util.go for making e2e
core framework small and simple:
- RestartKubeProxy: Moved to e2e network package
- CheckConnectivityToHost: Moved to e2e network package
- RemoveAvoidPodsOffNode: Move to e2e scheduling package
- AddOrUpdateAvoidPodOnNode: Move to e2e scheduling package
- UpdateDaemonSetWithRetries: Move to e2e apps package
- CheckForControllerManagerHealthy: Moved to e2e storage package
- ParseKVLines: Removed because of e9345ae5f0
- AddOrUpdateLabelOnNodeAndReturnOldValue: Removed because of ff7b07c43c
Remove the "OrDie" from the name (since it doesn't "or die") and add
an extra check that there is at least 1 node available, since many
callers already did that themselves, and many others should have.

Moving pod related functions from e2e/framework/pv_util.go to
e2e/framework/pod in order to allow refactoring of pv_util.go into its
own package.

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.
