Kitchen Door for strawberry_runners_postprocessor plugins

[DiegoPino]

Another improvement here:

• We should also have an API/smaller kitchen door way of providing Data for a configured @StrawberryRunnersPostProcessor. The idea is that e.g AMI can provide a ready OCR instead of having to go through the whole process. This requires some good planning but I was thinking maybe this:

• The Kitchen door will simply deposit for a Given Source File (the UUID) and a given ADO (the ID) a file candidate in a certain location.

• Every strawberry_runners_postprocessor instance will check before going full process mode if such exist.

  • If there, consume (but don't delete, mark to be composted by AMI really, since we might need it again) and/or transform.
  • If not do what it does, generate

Also: Every strawberry Runner output will also have a file (persisted) representation. This will allow you to build any simple "Text area" element to replace from S3/disk on OCR and trigger Solr reindex.
