CI failed, protocol_tests need to be updated
The HTTP request class doesn't have any implementations to insure case-insensitivity of the http headers. So we need to be mindful when populating these headers. Otherwise, the reqeust signature will be messed up. This change will ensure the protocol-specific default headers like content-type will be overriden by the serialized header if exists. For other headers added through middleware stack either by customization or users, it wouldn't affect signing or sending as long as the request doesn't contain same header names in different casing. All the internal headers will be consistent. But users should be careful when they are adding their own headers. We don't add middleware to lowercase all headers to prevent alternating the users' customizations. Ref: aws#1800
