Motivation
Implementing the missing PostObject operation, which is needed for pre-signed POST requests.
Changes
PostObject
is a bit of a weird operation in itself because everything is in a form, and the parser doesn't handle this kind of request right now, and maybe it shouldn't just for one operation. So most of the "parsing" is done directly in the provider method. I've added a bit more features than moto, as we now handle encryption parameters, tagging, and more response fields.
