WIP: Update quality profiles

- Add a new field "variant" in "metadata" section for quality profiles.
  "material" will only contain values such as "generic_abs", and
  "variant" will contain values such as "0.25 mm", "AA 0.4", etc.

- Reformat "metadata" section to have the following order:
   - setting_version
   - type
   - quality_type
   - weight
   - global_quality
   - material
   - variant
