A few things

  1. the kubelet -h text needs updating
  2. this should have a release-note
  3. it would be good if you can update kubelet-eviction.md design doc
  4. we will need a doc follow-on.

@derekwaynecarr I pushed the typo fix and updated the PR description with a release note.

From a documentation perspective (-h, design doc, kube docs) I don't think anything needs to be updated. The soft and hard thresholds don't call out explicitly that they support absolute values and percentages either.

If anything the docs should have said that --eviction-minimum-reclaim didn't support percentages before. With this PR, they are all uniform, accepting both percentages and absolute values.
