Cherry pick of #125197: [scheduler] absent key in NodeToStatusMap implies UnschedulableAndUnresolvable

[gabesaba]

cherry pick of #125197 on release/1.30

changes to make compatible with 1.30:

• Update wantEvaluatedNodes in schedule_one tests

/kind bug
/kind regression
/kind api-change

/sig scheduling

/assign @alculquicondor
cc @AxeZhan

Improved scheduling performance when many nodes, and prefilter returns 1-2 nodes (e.g. daemonset)

ACTION REQUIRED: For developers of out-of-tree PostFilter plugins, note that the semantics of NodeToStatusMap are changing: A node with an absent value in the NodeToStatusMap should be interpreted as having an UnschedulableAndUnresolvable status

Hi @gabesaba. 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.

#124735 was not cherry-picked, so yes, we need to update wantEvaluatedNodes in previously release. Looks right.
