It would be useful to print also types of the templates. Especially when the `delete` command requires the type.
We could either:
```
os["os_default_templates"].collect{|m| "%{config_template_name}s (%{template_kind_name}s)".format(m) }
```
or:
```
collection :os_default_templates, _("Default OS templates") do
  field :config_template_name, _("Name")
  field :template_kind_name, _("Kind")
end
```
