ADR: upgrading forms, workflows and catalogue items

Starting with allowing forms to have versions so that answers can be copied from old forms to the updated form based on field-ids. We need to have explicit tracking about the form updates and field ids.

What should REMS do in a situation where:
- Field has been removed from the updated form (where does the field content from old form go?)
- New field has been added (the field id's should stay the same for the fields that correspond to the old ones and the new field should get a new field id)

Also consider that there can be a situation where the question has been changed in the updated form but the field-id stays the same. Instruct against changing the questions but not field-ids.

Consider what kind of automation would help in administration.
