During a quick instance rebuild on Nova, it may remove a tap interface and then plug it in within the agent polling window. In this scenario the agent will not realize a device has changed and will therefore not ask the server for info an subsequently update its status. This will prevent the notification from being sent back to Nova that the vif plugging has finished so the VM will never resume state. This adds a new timestamp collection method to the common agent manager interface for devices that is used by the common agent loop to determine if a device has locally changed. The linux bridge implementation of it checks the timestamps on the tap interface's 'bridge' directory, which will change whenever the tap is added to bridge.
