Use interface operstate to determine nic status
Fixes lp bug 1555669
Currently _is_active_nic performs multiple checks to see if a link is live.
However some hardware such as Ethernet over USB devices fulfil this criteria.
This causes tripleo deployments to fail if automatic interface naming is used.
We can therefore use operstate to determine if the link is actually up.

This patch implements this.
Implements: better link state detection
Closes-Bug: #1555669
