Cool! I plan to add one more feature to allow operators to switch off
components of the score function. Currently, by only changing the key
to 'bytes', we aren't able to fully balance things because at some
point the pgs score gets too suboptimal and the overall score reaches
a min value.

I guess this point is debatable. On our clusters we use max_misplaced
= 0.01 and set the begin_hour end_hour to daytime hours so that by the
late evening, every day, the cluster is back to HEALTH_OK.
