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. Change-Id: I6d435d39e99ed0ff5c8b4883b6aa0b356f6cb4ae Closes-Bug: #1309110
