Re: Networking fact on linux should have logic for selecting IPs

The current implementation assumes that non default bindings are first in the `ip -o address` output, consequently the first binding is displayed.

Re: Networking fact on linux should have logic for selecting IPs

If we add another IP to `lo` interface

ip address add 1.1.1.1/24 dev lo

The output from Facter 3.x and Facter 4.x are different for `lo` ip

Facter 3.x
