List ideas for additional p11sak commands/function in this issue.

list-all
List all objects, regardless of its class or type.
The short listing will list - for those boolean attributes that do not apply the the object class. Besides that, the label and the object class/type should somehow be displayed.
For the long listing, we should then add support for knowing the attributes of all currently unsupported object classes, so that we at least can display the attributes properly.

remove-all / copy-all / set-attr-all
Similar to list-all, allow to remove, copy, modify an object regardless of its class.
