Several tooling improvements

[sawenzel]

• cleanup, fixes and adjustments in grid_submit

• a new script getReproducerScript.sh, which downloads a GRID reproducer script and modifies it to ensure automatic execution in apptainer:

  • the script needs a ALIEN_PROC_ID
  • creates a script reproducer_script_${ALIEN_PROC_ID}.sh which executes the job of ALIEN_PROC_ID within an apptainer environment (just as on the GRID)

• anchorMC now creates a reproducer script automatically
