Commits on Jul 12, 2021

  1. Fix a few problems 

    1) HighCPUForHosts panics when trying to generate a query for zero hostnames
2) Option parsing code used mongo-use-native rather than mongo-use-naive for "naive" schema
3) Helper scripts didn't have a way to choose between bucketized and document-per schema

  2. Fix GroupByTimeAndPrimaryTag and LastPointPerHost 

    1) GroupByTimeAndPrimaryTag used 2 sorts (on b and then a) when a sort on (a,b) was needed. The double sort is probably inefficient and only correct when a stable sort is guaranteed.
2) LastPointPerHost had a predicate on the "measurement" field which did not exist in the pipeline at that stage, so the query had an empty result
