Description

I would like to see this module include a 'remote_host' matcher, similar to the one in the caddy-remote-host module. I'm running this within docker, so it'd be preferable to refer to the containers based on their names instead of their IPs.

Please also consider adding an option to include the hostname in the debug logs rather than just the IP.

Contributor guide

Research direction
Study the existing matchers in caddy l4 (e.g., 'remote ip') and the referenced caddy remote host module. Implement a new matcher that extracts the remote hostname from the connection, considering Docker container names. Add an option to include hostname in debug logs instead of IP.
