"server list": "Image Name", "Image ID" columns

The `Image Name` column is shown by default (i.e.: without passing `--long`). E.g.:

```
$ openstack server list

```

The `Image ID` column is only available with `--long`. E.g.:

```
$ openstack server list --long -c Name -c "Image Name" -c "Image ID"
