Add getClienIPAddress helper

[sergiodxa]

The helper should receive a Request or Headers object and try to get the IP address from the following headers:

1. X-Client-IP
2. X-Forwarded-For
3. CF-Connecting-IP
4. Fastly-Client-Ip
5. True-Client-Ip
6. X-Real-IP
7. X-Cluster-Client-IP
8. X-Forwarded, Forwarded-For and Forwarded

Fly.io has fly-client-ip too 😬

@mcansh that's too new to be on the StackOverflow answer where I got the list of headers 😅

[sergiodxa]

@mcansh done #51, the nice thing is that adding new headers it's just adding to the list and that's all
