// plugins must return success or the pod will be rejected. PreFilter could optionally
// return a PreFilterResult to influence which nodes to evaluate downstream. This is useful
// for cases where it is possible to determine the subset of nodes to process in O(1) time.
// When PreFilterResult filters out some Nodes, the framework considers Nodes that are filtered out as getting "UnschedulableAndUnresolvable".
// i.e., those Nodes will be out of the candidates of the preemption.
//
// When it returns Skip status, returned PreFilterResult and other fields in status are just ignored,
// and coupled Filter plugin/PreFilterExtensions() will be skipped in this scheduling cycle.
