KEP-3659: ApplySet: kubectl apply --prune redesign and graduation strategy (kubernetes#3661)

* Initial KEP for improving pruning in kubectl apply

* Add design details

Co-authored-by: Katrina Verey <[email protected]>

* Add another open question

* Links, clarifications, ownerRef and GKNN explanations

* Follow-on to initial feedback, address some unresolved blocks

* Fix lint errors

* Add more detail about reference implementation (#2)

* Apply prune jan25 (#3)

* More clearly delineate specification vs kubectl details

* Move design details of spec to Design Details section

* Updates from synchronous conversation

* Remove leftover paragraph (kubernetes#5)

Not an alternative rejected any more, given applyset.k8s.io/inventory

* Justin has always been coauthor

* KEP-3659: production readiness etc (kubernetes#4)

Fill in the testing/ PRR sections.

* Fix test failures

* Prune: document confused deputy attack and mitigations

Likely pushes us to GKNN-derived IDs.

* Constrain applyset id

We just choose the constrained applyset id to prevent "applyset ID
impersonation".

* Update KEP and PRR metadata

* Enhance testing description

* ID vs name fixes

* Fixes from soltysh's review
