scouting: Add an endpoint for populating the match schedule

This patch combines the scraping library with the scouting webserver.
There's now also a new end point for the web page (or debug CLI tool)
to ask the server to fetch the match list. The end point is
`/requests/refresh_match_list`.

All the tests are updated. The `cli_test` downloads a 2016 ny_tr match
list that I downloaded from TBA. It should be a decent integration
test as it uses representative data.
