Tries to advertise valid default IP

During the first heartbeat, the heartbeater asks the agent to check
its advertised address; if the advertised IP is still the default
(None), the agent tries to replace it with the IP of the first network
interface it finds.  If it fails to find either a network interface or
an IP address, the agent raises an exception.
