> Log task statistics on TaskManager

>                 Key: FLINK-3263
>                 URL: https://issues.apache.org/jira/browse/FLINK-3263
>             Project: Flink
>          Issue Type: Improvement
>          Components: TaskManager
>    Affects Versions: 1.0.0
>            Reporter: Greg Hogan
>            Assignee: Greg Hogan
>            Priority: Minor
> Similar to how memory statistics can be written to the TaskMangers' log files by configuring
{{taskmanager.debug.memory.startLogThread}} and {{taskmanager.debug.memory.logIntervalMs}},
it would be useful to have statistics written for each task within a job.
> One use case is to reconstruct progress to analyze why TaskManagers take different amounts
of time to process the same quantity of data.
> I envision this being the same statistics which are displayed on the web frontend.
