[QarthO]

Siimilar to Cloudflare, Sucuri is a popular proxy/firewall service provider. This PR adds their trusted/secured ips for the nginx images

Found here under the 502:

It would be nice if this could be made easily configurable for any upstream ranges I want.

[QarthO]

This is already configurable by mounting an additional .conf file, which is what I'm doing currently

[hookenz]

I already feel that the trust is too wide.

I appreciate your time on this PR, but I had another issue where I had to restructure a bunch of web server configs and I was able to get this done on another PR:

#643

I would have merged this, but it would have been too complicated with the merge conflicts. I also separated out the configs so you're only loading what you need.

Thanks for your contributions! I look forward to reviewing another PR from you again in the future.

Appreciate the update, looking forward to checking out the restructure on the server configs
