Upload an external document
Uploads an external document (which does not depend on any document templates). Like `POST /document/{documentId}` the uploaded document can be queried, deleted and fetched by calling the corresponding method with received `documentId`. The document also has a date to which it is at least stored in the document store.
Currently only PDF documents up to a maximum size of 10MB are supported, without embedded links, scripts or attachments.
