    Fixed command list

    The cliff module expects an array of tuples however
    the array that this function was returning was an array
    of tuples that was also containing an array of values for
    the commands attached to each group and the
    cliff module wasn't liking it.

    The output now comes out looking like:

    | openstack.common | limits show |
    | | extension list |
    | openstack.baremetal.v1 | baremetal set |

    Change-Id: Ifa1c149cb5c66ba27dc72bf72d7c8f2f50e42f73
    Closes-Bug: 1545609

This issue was fixed in the openstack/python-openstackclient 2.4.0 release.
