Title: Support busboy truncated flag for files that exceed fileSize limit

From the busboy [README](https://github.com/mscdex/busboy/blob/master/README.md):
> `stream` also has a boolean property 'truncated', which indicates if the file stream was truncated because a configured file size limit was reached. It's probably best to check this value at the end of the stream.
