@StephanEwen I'll add the default initialization of ```counter``` while
merging.
Typing the counters to a ```SimpleCounter``` would affect a lot of other
classes though (especially since we can extend this to the
```OperatorIOMetricGroup```), so I would like to do that as part of another
issue.

> In 1.2-SNAPSHOT running a large scale job you see that the counts for
> send/received records are inconsistent, e.g. in a simple word count job we
> see more received records/bytes than we see sent. This is a regression from
> 1.1 where everything works as expected.
