binpacking simulator will now consider old nodes when trying to pack pods with topology spread constraints in order to avoid unecessary scale ups. The previous behavior did not consider that nodes that were once unschedulable within the pod equivalence group can can become scehdulable for a pod. this can happen with topology spread constraint since node scale ups can increase the global minimum, thus allowing existing nodes to schedule pods due to the increase in global_minimum+max_skew.
