[Share] Caddy2 available multi-WebUI config file

Related: #29

Caddy provides some awesome features such as automatic SSL, I prefer to use that in this case.

I'd like to share my config file here.

With this config file, you can:

• access qBittorrent built-in WebUI at [your-domain]/classic/ served at localhost:8080
• access qb-web at [your-domain], static file is located in /var/www/qb-web

[your-domain] {
        route /classic/* {
                uri strip_prefix /classic
                reverse_proxy localhost:8080
        }
        route /* {
                reverse_proxy /api/* localhost:8080
                root * /var/www/qb-web
                file_server
        }
        encode gzip
}

I hope this tip can be added into wiki, any further question and improvement suggestions is welcomed.
