* Switch CloudflareService from HttpartyCache to Danbooru::Http. * Purge cached urls from Cloudflare when a post is replaced and the md5 doesn't change. This happens when a corrupted image is replaced or thumbnails are regenerated. Before we purged urls when a post was expunged, which was unneeded because those urls can expire naturally. It was also wrong because the subdomains were hardcoded, the urls used http:// instead of https://, and we didn't account for tagged urls.
