STORM-1027: Use overflow buffer for emitting metrics
----
> Topology may hang because metric-tick function is a blocking call from spout

> Nathan had fixed the dining philosopher problem by putting a overflow buffer
> in the spout so that spout is not blocking. However, overflow buffer is not
> used when emitting the metric, and that could result in the deadlock. I
> modified the executor to use overflow buffer for emitting metrics and
> afterwards topology didn't hang.
