preemption is given by the formula:
numCandidates = max(numNodes &lowast; minCandidateNodesPercentage, minCandidateNodesAbsolute)

that play a role in the number of candidates shortlisted. Must be at least
0 nodes. Defaults to 100 nodes if unspecified.</td>

   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.</td>

   Shape specifies the points defining the score function shape, which is
used to score nodes based on the utilization of statically provisioned
PVs. The utilization is calculated by dividing the total requested
storage of the pod by the total capacity of feasible PVs on each node.
Each point contains utilization (ranges from 0 to 100) and its
associated score (ranges from 0 to 10). You can turn the priority by
specifying different scores for different utilization numbers.
The default shape points are:
1) 0 for 0 utilization
