Add "no results" table that render functions fall back on if results are None or empty sequence.

[pederhan]

Right now, we fall back on just printing an empty list with rich.print(), which is less than ideal when output format is set to table.

This should be implemented in a way that both compact table and harborapi table rendering can make use of it. That means it should be implemented on the function harbor_cli.render.render_table_full() somehow.
