A SharedKillSwitch is a provider for IGraphTShapes of FlowShapeTIn, TOut that can be completed or failed from the outside. A IGraphTShape returned by the switch can be materialized arbitrary amount of times: every newly materializedIGraphTShape belongs to the switch from which it was acquired. Multiple SharedKillSwitch instances are isolated from each other, shutting down or aborting on instance does not affect the IGraphTShapes provided by another instance. After calling Shutdown all materialized, running instances of all IGraphTShapes provided by the SharedKillSwitch will complete their downstreams and cancel their upstreams(unless if finished or failed already in which case the command is ignored). Subsequent invocations of Shutdown and Abort(Exception) will be ignored. After calling Abort(Exception) all materialized, running instances of all IGraphTShapes provided by the SharedKillSwitch will fail their downstreams with the provided exception and cancel their upstreams (unless it finished or failed already in which case the command is ignored). Subsequent invocations of Shutdown and Abort(Exception) will be ignored. The IGraphTShapes provided by the SharedKillSwitch do not modify the passed through elements in any way or affect backpressure in the stream. All provided IGraphTShapes provide the parent SharedKillSwitch as materialized value. This class is thread-safe, the instance can be passed safely among threads and its methods may be invoked concurrently.
