FindSimilarNodeGroups returns a list of NodeGroups similar to the given one.

IsNodeInfoSimilar returns true if two NodeInfos are similar enough to consider that the NodeGroups they come from are part of the same NodeGroupSet.

MaxAllocatableDifferenceRatio describes how Node.Status.Allocatable can differ between groups in the same NodeGroupSet.

MaxFreeDifferenceRatio describes how free resources (allocatable - daemon and system pods) can differ between groups in the same NodeGroupSet.

ScaleUpInfo contains information about planned scale-up of a single NodeGroup.
