[StarCluster] Easy way to delete more than 100k jobs

[Rayson Ho]

Is your local cluster using classic or BerkeleyDB spooling? If it is
classic over NFS, then qdel can be very slow.

One quick workaround is to hide the job spooling files manually, just move
the spooled jobs from $SGE_ROOT/$SGE_CELL/spool/qmaster/jobs to a private
backup directory.
