    Load-import failed due to lack of space in /scratch

    During a load-import operation, the iso file is copied to /scratch,
    a temporary folder (https://docs.starlingx.io/planning/kubernetes/storage-planning-storage-on-worker-hosts.html#root-filesystem-storage).
    Before the operation, it is checked if this folder has a free space of
    at least 3 times the ISO file, if not the load-import is aborted.

    This change enhances the message displayed to the user in order to
    give him some context and two solutions:
      - Delete some unused files from /scratch
      - Increase /scratch size

    Test Plan:
      PASS: After adding more free space to /scratch, the load-import
    operation must pass without error
