Improvement ideas

[64kramsystem]

• Cleanup incomplete data (like Fedora completed image) if a step is not completed
  • wget: delete/resume
• Add system info for each benchmark run
• Better separate variables
• Rearrange functions to follow the run order
• Add --force mode, in order to force running a step
• When checking which package(s) to compile, inspect individually
• Store logs in separate dirs
• plot_diagram: the scaling algorithm is not suited in some cases
  • When the right highest Y goes above the left highest Y, diagrams can't be compared
  • Idea: normalize all diagrams with a (perfect scaling) line that goes from 1 thread to nproc threads
