Update scale cmd help to display duration "units" in --timeout usage
release-note-none
`kubectl scale` has `--timeout` option, but the help info does not give accepted time units.
The help info gives default value 0 without a unit, potentially misleading a user into thinking they need to pass the numbered time only.

Partial #25382
This test creates three pods with QoS of besteffort, burstable, and
guaranteed, respectively, which each contain a container that tries to
consume almost all the available memory at a rate of about 12Mi/10sec.
The expectation is that eviction will be initiated when the hard
memory.available<250Mi threshold is triggered, and that eviction will proceed
in the order of besteffort, then burstable. Since guaranteed pods should
only be evicted if something charged to the host uses more resources
than were reserved for it, we currently end the test when besteffort and
burstable have both been evicted.
Note that this commit also sets --eviction-hard=memory.available<250Mi
to enable eviction during tests.

Allow expressing inodes in percentages for eviction
Per discussion here:
https://github.com/kubernetes/kubernetes/pull/28055#issuecomment-230078770
The amount of inodes per disk can vary, and our operators would prefer to express eviction in terms of percentage available. So independent of a disk having 3.2M or 12M of total inodes, its more convenient to just express eviction as saying if available inodes falls below 10 or 5 percent of total capacity then trigger an action.

pkg/util/exec: don't specify paths for echo
`ex.Command()` already searches the binary in PATH, no need to manually
specify it as `/bin/echo`. `pkg/util/exec` tests fail in non-conventional environments
due to this (e.g. NixOS).

Also, fix unit tests to have the same claim and volume sizes in most of the

e2e flake: real fix of PodAntiAffinity test
The fix in PR https://github.com/kubernetes/kubernetes/pull/30135 was wrong in using a wrong test condition for an already broken test.
### Summary
The test tries to launch a pod with an anti-affinity annotation, waits 10
seconds and then checks that it is still pending.
But the anti-affinity annotation does not forbid to launch that pod on just
another node that does not have the zone label at all.
This commit changes this behavior by labeling two nodes with the zone label
and then forcing the pod to be launched on one of those two nodes.
**I assume here that a non-existing label is considered as a different label value.**

SchedulerExtender: add failedPredicateMap in Filter() returns
Fix#25797. modify extender.Filter for adding extenders information to “failedPredicateMap” in findNodesThatFit.
When all the filtered nodes that passed "predicateFuncs" don’t pass the extenders filter, the failedPredicateMap hasn’t the extenders information, should add it, I think. So when the length of the “filteredNodes.Items” is 0, we can know the integral information. (The length of the “filteredNodes.Items” is 0, may be because the extenders filter failed.)
