Graceful reloads

Caddy does not require a full restart when configuration is changed. Caddy comes with a caddy reload command which can be used to reload its configuration with zero downtime.

caddy_container_id=$(docker ps | grep caddy | awk '{print $1;}')
docker exec -w /etc/caddy $caddy_container_id caddy reload
