**Commit Message** Previously, AWS signing has included the "content-length" header. However, Envoy's extproc filter strips it from the request as we are using CONTINUE_AND_REPLACE option to reduce the memory overhead. While we have still no clue as to why AWS doesn't complain when the request body is small, excluding content-length from the signing target headers will make the tests with both small and large bodies pass. **Related Issues/PRs (if applicable)** CONTINUE_AND_REPLACE was introduced in envoyproxy#636 to avoid sending a request body twice between Envoy and the ExtProc. --------- Signed-off-by: Takeshi Yoneda <t.y.mathetake@gmail.com>
