FORMS-211: (Designer) File submission template to be generated automatically

User Story description:

As a Form Designer (i.e., Health Authority user), I would like to the file submission template to be generated automatically based on the latest published version of a form.

This Story focuses on the bulk submission feature only:

The file submission template should be a .csv file containing all the columns that a submitter should be inputting as part of the submission.
This template should be automatically generated based on the form design and should include all the enabled input fields.
The column headers should be the labels of the fields

Business Rationale:

Currently, Health Authorities gather data from multiple facilities/operators to then submit this data to the Ministry of Health.

It is important for the Health Authorities to gather this data first as it feeds their own system. The current issue is that the HAs have no easy way to submit the data to the Ministry of Health. They can only do so through time consuming and painful manual form entries. As a solution they would like to have the ability to make batch submissions through a file upload functionality.
