Public bug reported:

We currently provide a few ways to create cell mappings for cells v2 in
nova-manage but we don't have a way to delete a cell mapping in case
there are some created erroneously.

We should provide a nova-manage cell_v2 delete_cell command which allows
deleting an empty cell mapping, it would take a cell uuid argument. If
the cell is not found by uuid we should return an error. If the cell has
mapped hosts or instances then it's not empty and we should return an
error.

Later iterations of the command might allow a --force option to delete
the host/instance mappings so that those could be moved to another cell,
but that would require some more thought.

** Affects: nova
