Use JUBE for messy-clams runs

Installation

on JURECA:
```
module load JUBE
```
Download and installation on cluster workstation:
- http://www.fz-juelich.de/ias/jsc/EN/Expertise/Support/Software/JUBE/JUBE2/jube-installation_node.html
- JUBE is installed in ~/.local/bin
- add ~/.local/bin to $PATH

JUBE script

Used files:
- Dummy makefile ${BASEDIR}/messy/mbm/clams/Makefile_jube
- Dummy MESSy script ${BASEDIR}/messy/util/xmessy_mmd.jube
- Dummy namelist directory ${BASEDIR}/messy/nml/MBM/clams_jube
  - (dir_dummy_nml in namelistParam in JUBE script)
If the script is called with tag comp, the basemodel clams is recompiled. The Makefile in subdirectory clams is replaced by the dummy makefile Makefile_jube with the current replacements (parameterset makeParam)
There is one parameterset for each clams namelist.

Run JUBE script

Example for JUBE script:
- messy-clams/messy/util/xmessy_jube_clim.xml
copy JUBE script to working directory and change namelist data in the script
run JUBE script:
```
jube run xmessy_jube_clim.xml [-t tag]
```

JUBE commands

jube run xmessy_jube_clim.xml [-t tags]

Run with Scalasca (on JURECA)

jube run messy_clim.xml -t time scorep_comp scorep

module load Scalasca
scalasca -examine messy_bench/00000x/000003_exe/work/scorep_clams24_run
scalasca -examine -s messy_bench/00000x/000003_exe/work/scorep_clams24_run

-> scorep.score is created
