	// PercentageOfNodesToScore is the percentage of all nodes that once found feasible
	// for running a pod, the scheduler stops its search for more feasible nodes in
	// the cluster. This helps improve scheduler's performance. Scheduler always tries to find
	// at least "minFeasibleNodesToFind" feasible nodes no matter what the value of this flag is.
	// Example: if the cluster size is 500 nodes and the value of this flag is 30,
	// then scheduler stops finding further feasible nodes once it finds 150 feasible ones.
	// When the value is 0, default percentage (5%--50% based on the size of the cluster) of the
	// nodes will be scored. It is overridden by profile level PercentageofNodesToScore.
