Show IP addresses for regular MAC addresses into `host list` output

[ggiamarchi]

Currently, the output looks like

+---------+---------------+---------------------------------------+-------------------+--------------+-------------+
|  NAME   | CONFIGURATION |                  MAC                  |     IPMI MAC      |  IPMI HOST   | POWER STATE |
+---------+---------------+---------------------------------------+-------------------+--------------+-------------+
| d1      | local         | 08:9e:01:fe:c4:7a | f4:52:14:b8:c0:7e | 08:9e:01:fe:c4:7b | 10.128.1.139 | On          |
+---------+---------------+---------------------------------------+-------------------+--------------+-------------+

In this case we should be able to visualize IP addresses for both MAC addresses 08:9e:01:fe:c4:7a and f4:52:14:b8:c0:7e into the output
