Why are we using DATE_TRUNC and not HISTOGRAM? Ideally it would be great if these were consistent.

The HISTOGRAM groups the data by INTERVAL but there is no "week" interval in Elasticsearch.
Perhaps there is a refactor needed to use DATE_TRUNC for the other time grains as well? I could do it, but as I am new to this community, could you let me know if I should do it in this PR or open a separate one for refactoring? 😄

@mikelv92 thanks for the explanation. I think it's ok to merge this PR as is, but if you're interested in doing a fast follow to change all the existing time grains to use DATE_TRUNC—which seems to be the blessed option—that would be great.
