Adding a DocumentService to clean up the FileService, and get Documents well seperated, as it seems likely be pulled out or seperated in the future, there is now a Documents api file as well, for the same reason.
Some other minor changes are just fixing white space to assure our code is linting correctly.
I removed _create_study_workflow_approvals from the base test, as we don't use approvals like this anymore.
Making all the lookup field names consistent.
Fixing the lookup service which was failing at times trying to find the correct field to use for building the lookup table.
Updating validation to check for additional fields and properties.
When connexion level errors occur, wrapping it in an API Error to be consistent.
Required Documents is becoming complicated, so making this it's own script task, removing it from study_info.py
The file_service is now very aware of this irb_documents file, so it will always need to exist. We seed this file
during setup, but it can be overwritten by the configurator.
