Fixed Memory Leak that caused keeping EventsManagerImpl for the whole run

[dimaopen]

1. Instead of adding PhysSimEventWriter which keeps a reference to the EventManager to the matsim controller listeners we add a small object that keeps a reference only to a terminated threadpool.
2. Do not init PrallelEventManagerImpl multiple times because it abandons blocked threads that are GC Roots. They keep their frames until the app exits.
3. Added a new parameter vmInformation.writeHeapDump in order to write a heap dump at each iteration so that we could debug memory leaks easier.
