Subject: [PATCH] Create Queries-per-second badge

The number of queries per second we handle is simply ginormous (> 20k!),
and I'd like to be able to communicate that to the user via a badge.

This commit has a GitHub Actions workflow that kicks off every six
hours to gather the current queries per second and create a JSON file
which is pushed to a gist which is used to create a shields.io badge.

Note: I'd normally test the Actions before I pushed, but it seemed
overly-complicated and brittle. So I'm taking the YOLO (you only live
once) approach, and pushing and hoping it works.
