Public bug reported:

devstack built 5 days before ,the param should be optional but it's
required now

jichen@ubuntu1604:~$ nova-manage cell_v2 update_cell --cell_uuid b674a67e-a4a3-414a-9507-f08407686d37
Updates the properties of a cell by the given uuid.

        If the cell is not found by uuid, this command will return an exit
        code of 1. If the properties cannot be set, this will return 2.
        Otherwise, the exit code will be 0.

        NOTE: Updating the transport_url or database_connection fields on
        a running system will NOT result in all nodes immediately using the
        new values. Use caution when changing these values.
