MINIFI-378: Resolve issues with shutdown. Took the approach to call
notifyStop at the destructor to avoid larger changes
> Shutdown can cause ProcessSessionFactory pointer to be deleted during use,
> causing page fault at shutdown

> If a thread within a processor uses the process session factory to create a
> session, the pointer will result in an invalid memory access, causing a seg
> fault. This is because the raw pointer is passed around and deleted. We
> should either convert this to a shared pointer or be more mindful of the
> variable's lifecycle given the complexity of processors will only ever
> increase. Further, we should not be deleting infrastructure components
> without ensuring all processors are finished.
