Add limit and detail optional case for node list api

[Kan]

There are two optional arguments for ironic node list api:

  --limit <limit> Maximum number of nodes to return per request, 0 for
                        no limit. Default is the maximum number used by the
                        Ironic API Service.

  --detail Show detailed information about nodes

These two cases are missed in tempest for ironic node list api.
