> STORM-2306 introduced a new configurable wait strategy system for these situations
>  * BackPressure Wait (used by spout & bolt)
>  * No incoming data (used by bolt)
> There is another wait situation in the spout when there are no emits generated in a nextTuple() or if max.spout.pending has been reached. This Jira is to transition the spout wait strategy from the old model to the new model. Thereby we have a uniform model for dealing with wait strategies.
