// We assume that the scheduler will make reasonable scheduling choices
// and assign ~N pods on the node.
// Although we want to track N pods per node, there are N + add-on pods
// in the cluster. The cluster add-on pods can be distributed unevenly
// among the nodes because they are created during the cluster
// initialization. This *noise* is obvious when N is small. We
// deliberately set higher resource usage limits to account for the
// noise.
