[feat] caddy-docker-proxy support ?

[accforgithubtest]

This is the handy tool that has been missing for caddy users, thank your really for creating this !

I use caddy-docker-proxy for configuring caddy using labels on docker compose files, and caddy-docker-proxy generates the caddyfile. This makes it more streamlined (imo) by having all reverse proxy configs for applications within the compose file itself.

My feature request / suggestion here is for generating appropriate labels for caddy-docker-proxy, and displaying it in the UI (may be side by side to caddy file, or using a toggle switch to change the output or may be separate tabs for caddyfile & caddy-docker-proxy configs).

I hope this request is not too far off from the intentions of this project.
Thanks again for creating this and cheers !
