Unit does not respect forwarded-ip when a proxy is in use

[cpund]

Current Behavior

Following the recommended process per the wiki for setting up TLS (https://github.com/netbox-community/netbox-docker/wiki/TLS), I've noticed that when viewing docker logs (from Unit) that all external requests (not the healthchecks) are written as if coming from the proxy, instead of implementing the X-Forwarded-For header to correctly identify the true originator of the request.

Expected Behavior

The Unit configuration file should include the forwarded section. This would allow us to define the source proxy and then ensure that the X-Forwarded-For IP gets passed for proper logging, instead of just reporting the IP of the Caddy proxy server.
