Changes:
- Relax stabilization requirement. Size may increase by 1 during
  stabilization. This is because HPA now stabilizes on max
  recommendation in the stabilization window. So if it sees a higher
  sample it should scale up. Resource consumer is imperfect and
  generates higher samples sometimes.
- Lower CPU load generated during stabilization period. This reduces
  risk of generating samples much higher than expected.
- Log status of HPA for easier debugging if the test fails.
- Increase expected number of millicores used to handle request to
  generate usage (see 7d2f3a0).
- Change int32 fields that were always cast to int before use to
  int.
- Update boilerplate.
