[awc] HTTP client ignores Content-Length if Body is stream.

[ArtBlnd]

Expected Behavior

HTTP client should respect Content-Length even body of request is stream.

Current Behavior

Content-Length header is removed by client itself.

Possible Solution

respect Content-Length header if present. also an enhancement, if first item of body stream is known as None it is better set Content-Length to zero. not inserting chunked encoding header.

Steps to Reproduce (for bugs)

Send request with empty stream.

Context

Cloudfront will reject you.
