✨(api) allow forcing ID when creating a document via API endpoint

We need to be able to force the ID when creating a document via
the API endpoint. This is usefull for documents that are created
offline as synchronization is achieved by replaying stacked requests.

We do it via the serializer, making sure that we don't override an
existing document.
