Title: Error checking and reporting on interface ufw rule

If someone fails to specify the direction on a rule for an interface, they are met with this message:

```
failed: [my_super_cool_server] => {"failed": true}
msg: ERROR: Invalid token 'on'
```

This just provides a check and a more informative message.
