This launcher, an analogue to the qsub and bash launcher classes, will be used on blanca. I hardcoded the Slurm `module load` call into the class. This needs to be changed, perhaps read from some environment setting.
The purpose of the run script is to call `module load slurm/blanca`, which has to done before calling the launch script (which includes SBATCH commands), and which can't be called through subprocess.call. To do this, I added a new class attribute, `_run_script`, a new attr to SbatchLauncher, `run_script_path`, and I overrode several methods.
This was causing jobs to fail on the CSDMS compute node on blanca. (They would run on the login node.) @mcflugen pointed out that this may be a hardware issue--the compute nodes may vary. I'll try to isolate this and notify RC.

*software, not hardware, issue in 3517098. We likely just need Qt installed. |
I experimented with os.system to see whether it behaved differently. Answer=no.

The new CSDMS cluster, blanca, uses Slurm as a job scheduler instead of Torque, which implies a new Launcher class.
