Description of problem:

The customer wants to use the IPMI system facts to automatically generate the BMC interfaces.

Business Case:

When adding the BMC proxy to Sat6, it would be helpful if hosts could
automatically create their IPMI interfaces via system facts.

Technical Requirements:

Add BMC interfaces in a similar manner to how other network interfaces
are added from system facts.
Add a "default" BMC user/pass to the admin config.
