Basic command line script to input NGS / Chemo toy data (+tests)

Django script (init shell or django command).

• Override https://docs.djangoproject.com/en/2.1/ref/files/storage/
• Keep it generic to data type
• Copy to ZFS partition.
• Successful file transfer check (before db save)
• Insert metadata in django app db (require that upload is done with metadata)
• Identify storage folder hierarchy / structure
  -> Wanna keep some sort of organization but can very quickly fall into "graph" (relational) territory... Keep it simple. (ZFS partition not meant to be accessed by regular users for now - files will be copied)
  -> Each file in its own SHA1/MD5 folder?
• Elaborate various data models (generic, NGS specific etc...)
