ipmi-config metrics

[robbat2]

I'm looking at a fleet with ipmi_exporter running locally on the nodes, and I'd like to export some of the ipmi-config values via labels.

ipmi_config_info{lan_ip_address="...",bmc_mac_address="..."} 1

Would this be accepted as a PR?

Yes, sounds good. It would become a new collector. Let me know if you need any pointers.
