caddyfile: expand environment variables within caddy files (#3082)

Browse Source 
Small expansion to the work done in https://github.com/caddyserver/caddy/pull/2963 which simply calls `os.ExpandEnv` so env vars like `{$URL}` where `$URL=$SCHEME://$HOST:$PORT` (contrived) get the expanded $SCHEME, $HOST, and $PORT variables included
