as per keystone identity v2 api here http://api.openstack.org/api-ref-identity.html#identity-v2 shouldn't the username be returned as the key ```name``` not as ```username```?

Here's the sample response from the openstack api docs, notice the ```"name":"jqsmith"```
```
{
   "user":{
      "id":"u1000",
      "name":"jqsmith",
      "email":"john.smith@example.org",
      "enabled":true
   }
}
```
