ENH: Large SGE jobs were overloading on qstat

When large jobs were run with SGE, the accumulation of
qstat queries was causing a massive load on the cluster
server, and was affecting overal system performance.

This modification queries based on userid, stores information
about all that users jobs (both running and recently finished),
subsequent queries are then addressed by looking at the cached
values first, then only updating with a system qstat call
periodically.  This change so that qstat is called on a
more reasonable replication time frame.

User can supply externally supplied version of qmake.

Prevent DOS style of attacks on the batch processing
server by preventing continuous queries by many jobs.

This was affecting the performance of the entire server
and the excess load of querying when jobs were done in the
niavie way was affecting the performance of dispatching new
jobs.

The following two scripts can be used as plugin_args to
provide cached versions of qmake suitable for running
huge jobs.

plugin_args=dict(template=JOB_SCRIPT,
            qsub_args="-S /bin/bash -cwd -pe smp 1-12 -l h_vmem=19G,mem_free=9G -o /dev/null -e /dev/null " + CLUSTER_QUEUE,
            qstatProgramPath=qstat_immediate.sh,
            qstatCachedProgramPath=qstat_cached.sh))
