Message:

Added Shutdown as choice to ControllerChoices.

• new helper app Shutdowner that shuts down Server.
• TESTFIX: Changed regression test Fragmentation/Automation where now Shutdowner is uses instead of Jobadder with 0 jobs to power down controller socket.

• src/Fragmentation/Automation/FragmentController.cpp (modified) (3 diffs)
