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

Required 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 specified in namelistParam in JUBE script)
JUBE script, e.g. ${BASEDIR}/messy/util/xmessy_jube_clim.xml

JUBE script

Example for JUBE script:
- messy-clams/messy/util/xmessy_jube_clim.xml
Inside the script there is one parameterset for each clams namelist.
The namelist input is specified in these parametersets.
The dummy entries in the namelists ${BASEDIR}/messy/nml/MBM/clams_jube/*.nml will be substituted with this input and copied to the namelist directory (NML_SETUP).
Attention: Namelists in directory NML_SETUP will be overwritten if they already exist !
The specifications in the parametersets jobscriptParameter and xmessy_mmd are used to substitute the dummy entries in the messy script ${BASEDIR}/messy/util/xmessy_mmd.jube.
The messy-script xmessy_mmd.jube with substitutions is copied to the working directory (name: xmessy_mmd.$EXP_NAME).

Run JUBE script

copy JUBE script to working directory and change namelist data in the script
run JUBE script:
```
jube run xmessy_jube_clim.xml [-t tag]
```
If the script is called with tag comp, the basemodel clams is recompiled.
Attention: The Makefile in subdirectory clams is replaced by the dummy makefile Makefile_jube with the current substitutions (parameterset makeParam)

JUBE commands

Run with Scalasca (on JURECA)

module load Scalasca

jube run messy_clim.xml -t time scorep_comp scorep

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
