// MakeNodesAndPodsForEvenPodsSpread serves as a testing helper for EvenPodsSpread feature.
// It builds a fake cluster containing running Pods and Nodes.
// The size of Pods and Nodes are determined by input arguments.
// The specs of Pods and Nodes are generated with the following rules:
//   - Each generated node is applied with a unique label: "node: node<i>".
//   - Each generated node is applied with a rotating label: "zone: zone[0-9]".
//   - Depending on the input labels, each generated pod will be applied with
//     label "key1", "key1,key2", ..., "key1,key2,...,keyN" in a rotating manner.
