Remove the Downloads::File class. Move download methods to Danbooru::Http instead. This means that: * HTTParty has been replaced with http.rb for downloading files. * Downloading is no longer tightly coupled to source strategies. Before Downloads::File tried to automatically look up the source and download the full size image instead if we gave it a sample url. Now we can do plain downloads without source strategies altering the url. * The Cloudflare Polish check has been changed from checking for a Cloudflare IP to checking for the CF-Polished header. Looking up the list of Cloudflare IPs was slow and flaky during testing. * The SSRF protection code has been factored out so it can be used for normal http requests, not just for downloads. * The Webmock gem can be removed, since it was only used for stubbing out certain HTTParty requests in the download tests. The Webmock gem is buggy and caused certain tests to fail during CI. * The retriable gem can be removed, since we no longer autoretry failed downloads. We assume that if a download fails once then retrying probably won't help.
