What type of PR is this?

/kind bug
/kind cleanup

What this PR does / why we need it:

Modify scale down set processor to add reasons to unremovable nodes so that planner can have these nodes excluded as unremovable nodes with reasons

Special notes for your reviewer:

  1. Moved NewTestProcessors to be under processors/test to avoid the following circular dependency : nodes (ScaleDownSetProcessor)-> ScaleDownContext-> resource -> test (core/test/common)-> nodes (ScaleDownSetProcessor)
  2. On adding unit tests for planner I noticed that MaxNodesProcessor is being called before AtomicResizeFilteringProcessor which might cause filtering removable nodes on both calls ending up with less nodes to be deleted than we should be deleting, created an issue for it cluster-autoscaler : MaxNodesProcessor is being called before AtomicResizeFilteringProcessor #7342

Does this PR introduce a user-facing change?

NONE

Hi @abdelrahman882. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

Thank you for the change! Especially for adding unit tests where they were missing.

I've got some suggestions but the comments are all relatively minor.

I think you can remove the isValidCandidatesFiltering function now. Otherwise
