Adding the StorageServiceMBean stub
This adds a stub of the StorageService. After applying it, it will be possible to use JConsole to connect to the process and run any of the command and inquire all the properties. Some deprecated methods uses RepairParallelism class, an empty implementation for it is added. It would be removed with future version of the MBean, when those methods will be removed from the MBean As this is a stub, the only effect is a printout on the screen.
