By default, Werkzeug would require the entire file (be it an OVA or image file) to be uploaded and saved to a temporary, fake file under `/tmp`, before any further processing could occur. This blocked most of the execution of these functions until the upload was completed. This entirely defeated the purpose of what I was trying to do, which was to save the uploads directly to the temporary blockdev in each case, thus avoiding any sort of memory or (host) disk usage. The solution is two-fold: 1. First, ensure that the `location='args'` value is set in RequestParser; without this, the `files` portion would be parsed during the argument parsing, which was the original source of this blocking behaviour. 2. Instead of the convoluted request handling that was being done originally here, instead entirely defer the parsing of the `files` arguments until the point in the code where they are ready to be saved. Then, using an override stream_factory that simply opens the temporary blockdev, the upload can commence while being written directly out to it, rather than using `/tmp` space. This does alter the error handling slightly; it is impossible to check if the argument was passed until this point in the code, so it may take longer to fail if the API consumer does not specify a file as they should. This is a minor trade-off and I would expect my API consumers to be sane here.
