Tune `hpa.targetAverageValue` for Review Apps sidekiq and unicorn
Quoting @twk3 in !20533 (comment 253480279)
one thing to explore going forward is tuning the hpa.targetAverageValue for sidekiq and unicorn. You're still relying on the defaults, which may be causing you to bring up more pods than needed if you are expecting your pods to have higher averages than the defaults. Particularly for sidekiq, the targetValue appears much lower than your requested cpu, depending on the number of sidekiq jobs you have you might be overscheduling pods vs what you need.
