All of our uploads now have the metadata about the job set on them in
S3. So this commit moves to using that metadata, if it’s there, instead
of the data in the body of the post request.
The aim of this is to stop the admin app having to post this data, which
means that it won’t have to keep this data in the session for the
while doing the file upload flow.
- Also convert the files info to upper() for comparison rather than lower
because original file names are in upper case. The unit tests contain examples of the returned lists.
this means that if the task is accidentally ran twice (eg we autoscale
notify-celery-worker-beat to 2), it won't send letters twice.
Additionally, update some function names and config variables to make
it clear that they are referring to letter jobs, rather than all letter
content
