func NormalizeScore 

func NormalizeScore(scores framework.NodeScoreList) *framework.Status

NormalizeScore in Score Extension. 

Reused by all plugins whose scores might go beyond 0(framework.MinNodeScore)--100(framework.MaxNodeScore)

func PreFilterFragGpuRatio 

func PreFilterFragGpuRatio(nodeInfoList []*framework.NodeInfo, typicalPods simontype.TargetPodList) (float64, *framework.Status)

PreFilterFragGpuRatio return the fragGpuRatio (0.0-1.0) of the current cluster, 

	 i.e., how many of the idle GPUs are fragment.
  Its output should be cached to plugin.fragGpuRatio to avoid re-computation.
  It should be called before filter to avoid the change of visible nodes.
