how to configure cloudflare proxy (CDN) with heroku SSL

You may encounter ACM error with heroku SSL + cloudflare proxy. Official doc on heroku does not recommend to do so. Cloudflare's doc is not clear on this as well. Actually, it is very easy to configure them right if you want CL's proxy and heroku's SSL management.

1. remove SSL from heroku if you have one
2. remove CL's proxy if you have it configure
3. add heroku's SSL
4. after heroku's SSL is up (ACM shows green indicator), add CL's proxy.
5. verify it after DNS is propagated.

That's it!
