Cloudflare proxy support for flask application.

It gets client ip from cloudflare headers and can allow request from cloudflare ips only. If you are behind a proxy remember to use werkzeug.middleware.proxy_fix.ProxyFix, alternative you can override CloudflareRemote.get_remote() in order to fetch the correct client ip for example via HTTP_X_FORWARDED_FOR.
