systemd-docker's cli looks like ```rancher run --rm --name abc``` , the equivalent of that in this project would be ```rancher run rm --name abc ``` (notice no "--" before rm). I think this is also cleaner. 

In order to do that, I parse out ```rm``` and ```create``` manually. That said, flag.Args() is still a good idea for this, as it would give me the first non-flag arguments. eg. ```[]string{"container", "create", "--name"}``` and I wouldn't have to loop through ```--url http:/... --accesskey A3fdsFWSfsf```, which i'm doing right now
