Title: [AWS|Storage] update post_object_hidden_fields to use signature v4

I missed this during my first pass to update everything to v4. I've tested this with some sample code I threw together and it does let you upload files to S3 but this isn't something I use day to day - can anyone who does use it verify I haven't changed behaviour?
