This checks the AWS instance data URL to see if there's a pending shutdown for the instance. This is useful for AWS spot instances. If there is a pending shutdown posted to the instance data URL, we'll use the result of this function break out of the processing loop and shut everything down ASAP before the instance dies. Returns ------- bool - True if the instance is going to die soon. - False if the instance is still safe.
