Include Content-MD5 in signed headers

[USSRLivesOn]

Per the AWS docs, "The headers used for request signing are: content-md5, content-type, date, and anything that starts with x-amz-." It looks like content-md5 is excluded currently from the set of headers that is signed by requests-aws4auth, but it should be included. Our current workaround is just to pass the full set in include_hdrs kwarg, but would be good to have the defaults updated.

I'm running into this issue now, can you provide an example of this workaround?

I got it working by passing the include_hdrs argument to the constructor:

AWS4Auth('<ACCESS ID>', '<ACCESS KEY>', 'eu-west-1', 's3', include_hdrs={'host', 'content-type', 'date', 'x-amz-*', 'content-md5'})
