> Create a common interface for all Trident spout
> -----------------------------------------------

> Key: STORM-1221

> Currently {{IBatchSpout}}, {{IOpaquePartitionSpout}}}, {{ITridentSpout}} and
> {{IPartitionedSpout}} are all top-level interfaces. The lowest common
> ancestor of their parent interface is {{Serializable}}. There is no clear,
> single interface in Trident to mark these class are spouts / data sources.
> The abstraction is beneficial when components on top of Trident (e.g.
> StormSQL) need a notion of data source.
> This jira proposes to tags all the spouts above with a common marker
> interface.
