Named Plan ExecutorService pools, Fixed WebServer thread leak on reload

Browse Source 
WebServer ThreadPoolExecutor was never shutdown, as it was assumed
HTTPServer.shutdown() would perform that.
In extreme cases 250 reloads could lead to a OutOfMemoryException due to
Heap size allocation for threads not being possible.

Change: Shut down ThreadPoolExecutor manually.
