fix(network_routes): missing node ip -> error log (#904)
Before we used to raise an error when a node was missing an IP, but it
turns out that this is not a required attribute of a node. And while it
is rare that a node would be missing an IP address, a node doesn't
require an IP address or a name or really much of anything in order to
exist.

This brings us to stronger conformance with the Kubernetes API and makes
it so that kube-router logs errors rather than changing it's health
status and potentially causing cascading failures across the fleet if a
user adds a node like this.
