Bare metal list doesn't display MAC address or task state

[Phil Day]

nova baremetal-node-list doesn't display the MAC address because it is nested in the interfaces list, not a top level field in the object

It also doesn't display the task state, which is generally needed when looking at a list of nodes.

    Fix mac address and task_state in baremetal-node-list

    Currently nova baremetal-node-list doesn't display the
    list of MAC addresses for each node because this is part
    of the interfaces object, and not a top level field.

    It also doesn't display the task state, which is very useful
    when trying to find which nodes have failed to build.

    This change fixes both issues
