anchor.diff:  <8> Use the `metrics` parameter for memory utilization.
   <9> Specify `memory` for memory utilization.
   <10> Set to `Utilization`.
  -<11> Specify `averageUtilization` or `averageValue` and a memory value.
  +<11> Specify `averageUtilization` and a target average memory utilization over all the Pods,
