[Bug] X-Amz-Content-Sha256 is not allowed for upload

[mrister]

Error: X-Amz-Content-Sha256 is not allowed
With: Latest aws-sdk-js (doing client side uploads)

I was running a containerized image for demo purposes and got 'X-Amz-Content-Sha256 is not allowed' on requests.

Latest master has support for setting CORS headers but it is unreleased. This actually helps but I needed to make my own image to be able to use it.
So until this gets released or fixed you can use my image to pass CORS headers (not really production grade because it takes fake-s3 from master)
