      Description

      IMPALA-8946 pointed out that we didn't correctly expose our metrics as histograms. Histogram metrics are meant to expose enough of the histogram state that prometheus can do additional computations on it. See https://prometheus.io/docs/practices/histograms/.

      We could consider exposing the histograms in this way so that there's more flexibility about additional computations we can do on the histograms.
