BGQ - Added RebootQOSList option to bluegene.conf to allow an implicate
reboot of a block if only jobs in the list are running on it when cnodes
go into a failure state.
BGQ - Add preempted flag for bg_requeue_job
BGQ - Added "cleaning" flag for handling when a job is being cleaned of
a block.
Remove duplicate variable.
BGQ - Rewrite of RebootQOSList logic to be slightly more robust
BGQ - Move logic to a place that will not wait for a job to finish.

Problem with previous method is if a job where the cnode failure happened
had the --no-kill option the block would be locked up until a job finished.
BGQ - Handle when a block goes gets a 'D' action
