Guess primary address

[Solvik]

Netbox has the ability to flag an IP as Primary address for a Device

Since it's tied to the user workflow, I'd say we could enable this guess with a config argument and use the following workflow

• parse the route table
• find the source ip of the default route
• flag this IP as Primary adresss

[ThomasADavis]

interface = netifaces.gateways()['default'][netifaces.AF_INET][1]

will tell you which interface has the default route.

Doesn't seem to handle every case:

>>> import netifaces
>>> netifaces.gateways()
{'default': {}}

In my case IP are announced via exabgp
