Commands fail poorly if container is not running

[emcniece]

For example, executing service nginx reload on an Nginx container that is down renders the following error:

INFO[0091] Executing notify command 'rgon-exec -name=rgon-proxy-nginx-1 -cmd="service nginx reload"'
INFO[0091] [rgon-exec -name=rgon-proxy-nginx-1 -cmd="service nginx reload"]: "Executing [service nginx reload] on container [rgon-proxy-nginx-1]"
