Convert GenerateLordnCommand to tm (#1091)

* Convert GenerateLordnCommand to tm

This makes use of QueryComposer and adds a `list()` method to it.

Since there was no test for GenerateLordnCommand, this also implements one.

* Changes requested in review

* Add test for list queries

* Stream domains instead of listing them

* Reformatted
