> mesos 0.25.0 version if slave startup flags --containerizers=docker, using
> docker container the rest api "/monitor/statistics.json" output have no
> timestamp field,while if the mesoscontainer the output will have the
> timestamp field.
> So if we use docker container we maybe cann't calculate cpu utilization based
> on timestamp, futhermore the "timestamp" is the required filed in
> ResourceStatistics message.
