Task #9764: Provide input filename differently to PyBDSM to allow it to derive a proper logfile location

Task #8437: Add support for global fs in node scripts to prevent rsyncing files within the same filesystem

Task #8991 Change for the generic pipeline -> executable_casa.py: Merge with the multi-epoch version.

Task #8679 Fixes to run wsclean with multiple input files. Exact matching during inputkeys replacement instead of substrings. Loop break condition change as requested by David.

Task #6559 Bring the mapfile argument for subpipelines in line with the syntax for regular recipe steps (mapfile -> mapfile_in)

Task #6559 busy week update. string replacement: parameters to change can be easier be put on top of the parset. syntax corresponds to jinja2 in factor. fixed nested loops and break condition from python steps. started api for creating pipelines from python console.

Task #6559 Added a calibrate stand alone node script that directly calls bbs-reducer and not the calibrate-stand-alone shell script. This way bbs-reducer gets called by the pipeline infrastructure and not as a subprocess called by a different mechanism. Also the order of the arguments should not matter anymore when they are given as parset arguments (long options).

Task #6559 python plugins as node script. they can return a dict that gets saved by the master script as mapfile and can be used as input for later steps.

Task #6559 small update changing the automatic naming of results. names were too long and now only contain the last stepname the data went through.

Task #6559 Update from march busy week. Functionality for extreme peeling preparation and bug fixes.

Task #7491: Small rename of variables. Add output of correct files per image (including skip set), not used in the pipeline but for validity
