Can't filter analytics by HTTP method #401
Description
In the admin analytics, you can't actually filter the results by "Request: HTTP Method." Trying to filter to POST/GET/DELETE/etc requests via this drop down always results in 0 results.
However, you can filter by this field using the advanced query syntax: https://api.data.gov/admin/#/stats/logs?query=&search=request_method%3APOST
I haven't dug into it, but I suspect something is amiss with the case-sensitivity handling for this field, since I think this is one of the few fields that we handle case-insensitively, but by uppercasing everything (rather than how we normally downcase other fields we want to handle case-insensitively).
