OSF Schema Responses API

Schema Responses contain user supplied responses to a Registration Schema. A Schema Response aggregates all of the the responses for a given version of a Registration's Registration Schema. Schema Responses are created when a Registration is completed. Once a Registration is completed the Schema Responses for a Registration can be revisied and updated by using it's associated action endpoints. There are a few states for Schema Responses: - `initial` is the state of a Schema Response on a newly registered Registration, to edit a Schema Response you must create a Schema Response Action that triggers a new submission. - `in_progess` is the state of a Schema Response where the response is editable and still private, Schema Responses are editted via a PATCH request as specified below. - `unapproved` is the state of a Schema Response where edits have been made and "locked-in", now contributors have the ability to reject the changes, however if they are not rejected changes are automatically approved after 48 hours. If `unapproved` Schema Responses are rejected, they are returned to the `in_progress` state. If `unapproved` Schema Responses are approved they either enter an `approved` state or go into a `pending_moderation` to be accepted or denied by a moderator. - `pending_moderation` is the state of a Schema Response where moderators have an opportunity to reject or approve a Schema Response that has been approved by it's contributors. This state is only reachable for Schema Responses that are associated with a Registration that has Registration Provider a moderated workflow. - `approved` is the state of a Schema Response where it is public and immutable, in order to update an approved Schema Response a new one must be created.
