Changed both target and variable names from trace to trace_experiments and TRACE to TRACE_EXPERIMENTS

[harmonie]: Merge branch 'harmonie' of https://earth.bsc.es/gitlab/ces/automatic_performance_profiling into harmonie

[harmonie]: refactored function scatter_plots + fixed division by zero in function_info_csv and function_curated_summary. Added file better parsing inputs.

Minor refactorization to make the scalability and traces copy work with other models, plus increase roubstness wrt workflow part 1

[Issue#44]: function scatter_plots now takes as input name of lines to plot. Moreover moved function from curation.py to parser.py, that was a very weird logic ...

[Issue#44]: small refactoring of read_argument function, and added hardcoded dictionary for generating different scatterplot
