Remove msa_fix_ld, its no longer necessary since 20190723 maintenance. But we have to load a specific ParaStationMPI

Communication with the psgwd has to be ensured via loading the software module **pscom-gateway** either via ``xenv`` or the ``module`` command.
**JURECA Booster, Current MPI Workaround (April/May/... 2019)**
For the time being, prefixing JURECA **Booster** binaries with ``msa_fix_ld`` is necessary. This is due to the fact that the installed libmpi version does not support the psgwd. We hope this will go away soon.
``msa_fix_ld`` is modifying the environment, so it might influence the modules you load.
**JURECA Booster, Current MPI Workaround (July/... 2019)**
For the time being, a specific version of ParaStationMPI from the Devel-2019a Stage must be used. This is due to the fact that the default ParaStationMPI version for the Booster does not support the Gateway Protocol. We hope this will go away soon.
To load the corresponding ParaStationMPI, use the code snippet below for the **booster** pack of the job.
.. code-block:: none
#!/bin/bash
export PSP_PSM=1
export LD_LIBRARY_PATH="/usr/local/jsc/msa_parastation_mpi/lib:/usr/local/jsc/msa_parastation_mpi/lib/mpi-hpl-gcc/:${LD_LIBRARY_PATH}"
$*
srun ... : xenv -P -U /usr/local/software/jureca/OtherStages -L Stages/Devel-2019a [ -L ... ] -L ParaStationMPI/5.2.2-1 <binary> [ : ... ]
