The python script builds the interface between the scheduling-aware
routing and the batch system (SLURM in this particular case). The
scheduler-sar-interface.py script analyzes the jobs running on the
system, compares this state to a previous state (if available), and
triggers an rerouting of the fabric through the opensm, when the two
states differ significantly.

The output of scheduler-sar-interface.py is stored in
/dev/shm/batch_jobs.conf and opensm needs to start with
'--batch_job_file /dev/shm/batch_jobs.conf', or the equivalent option in
the osm.conf file to make use of the feature.

Changes to Makefile.am enables the automatic installation of
scheduler-sar-interface.py into the sbin directory of the installation
directory.
