temporary storage

The main goal of this merge request is to address issue #42 (closed) So while running corsika parameter_card process, corsika will temporarily store the files and logs at the scratch space in computing nodes and automatically move them to fefs once the job is finished. An automatic cleanup of the scratch space occurs.

The merge request also addresses some smaller issues that were encountered during xmas period, when the production was started. The issues were corrected on spot, but were not propagated to the repository. The main is the creation of a jobs directory for corsika jobs.

Closes #42 (closed)
