Introduce a new Caddy module within opnsense-config to manage Caddy server configurations. This includes enabling/disabling Caddy, setting ports, and reloading/restarting the service via OPNsense shell commands. Additionally, provide a sample Caddy configuration file for PXE booting and a test file in the pxe-http-files directory.
Due to the current setup being a mix of separate repositories with gitignore and rust workspace, a few options are required for cargo-watch to have the desired behavior :
RUST_LOG=info cargo watch --ignore-nothing -w harmony -w private_repos/ -x 'run --bin nationtech'
This will run the nationtech bin (likely private_repos/nationtech/src/main.rs) on any change in the harmony or private_repos folders.
