Finish an upload started with create_upload and begin processing. Pass the
`video` id (hashid) returned by create_upload, AFTER you have PUT the file
bytes to its upload_url.
Queues the video for processing and returns its `id` and current `status`.
The outcome (`processing`, or `pending_credits` if the team is out of
credits) is settled a moment later, so poll get_video_status for it. If the
file hasn't been uploaded yet, an error is returned: upload it, then retry.
