- Improved scheduling performance when many nodes, and prefilter returned 1-2 nodes (e.g. daemonset)
  
  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. ([#125197](https://github.com/kubernetes/kubernetes/pull/125197), [@gabesaba](https://github.com/gabesaba))

- Changed NodeToStatusMap from a map to a struct and exposed methods to access the entries. Added absentNodesStatus, which informs the status of nodes that are absent in the map. For developers of out-of-tree PostFilter plugins, ensure to update the usage of NodeToStatusMap. Additionally, NodeToStatusMap should eventually be renamed to NodeToStatusReader.
