Looks good. You'll need to either update the golden results on a few QoR failures (I checked and they all look fine -- small circuits and more got better than got worse), or we'll need to combine this with Mohamed's cluster retune PR so you piggyback on his golden results. @MohamedElgammal

Updating branch so it has Mohamed's cluster parameter change. Then @amin1377 will update the various nightly golden results, as we're likely to have some re-sync needed there.
