Add a formal cleanup phase to the scheduler flow.
-add a --cleanup or -C option to autoserv, which runs a new control segment, cleanup.  this option and control segment obsolete the old -b option and reboot_segment control segment.
-change the RebootTask in the scheduler into a more generic CleanupTask, which calls autoserv --cleanup.
-change the host status "Rebooting" to "Cleaning"
