Subject: [PATCH] Fallback if container has no IP

Sometimes containers will not be assigned an IP (after reboot or due to misconfiguration). This leads to an incorrect "server <missing ip> down;" line in default.conf and crashes nginx.
@therealgambo  provided a fix for this: https://github.com/jwilder/nginx-proxy/issues/845
