Description
When an app name is not provided for `deis` commands technically requiring one the current default is to return the raw `404 Not Found` response from the k8s api:
```
$ deis config:list
Error:
404 Not Found
detail: Not found.
```
It would be nice if the command could inform the user of the need/requirement to pass the app name (in the form of `-a app_name`) to properly proceed. (Basically, if the command hasn't been invoked with this parameter, send some default message to that effect)
