> Currently, pipeline elements implement an interface that provides the three methods onInvocation, onEvent and onDetach.
> In future enhancements, we plan to introduce features that require actions at pipeline creation time, e.g., to create a virtual data stream once a pipeline is stored. To avoid installing/deinstalling such a stream at every start/stop of a pipeline, the wrapper interfaces should be extended/refactored as follows:
>  * Add an onPipelineStored method to the pipeline element definition
>  * Add an onPipelineDeleted method to the pipeline element definition
>  * Rename onInvocation to onPipelineStarted and onDetach to onPipelineStopped for clarifying the scope of the provided methods
>  * Ensure backwards compatibility by introducing API versioning for pipeline element endpoints
>  * Extend the endpoints to handle onPipelineStored/Delete calls, HTTP Post/Delete for Store/Delete and HTTP PUT for Start/Stop
