Update HttpUtil responseParsing to handle multiple HTTP responses

[sf-cg]

Context

Within our projects we use a proxy when connecting to some services, and when doing this we get an extra HTTP/... in the response string that is then parsed. Similar to the 100 continue issue, but ours were 200 OK response from the proxy added ontop

What has been done

• the HttpUtil parsing of response has been update to only get the headers after the last HTTP/ line, which ideally should make this much more flexible than just stripping any 100 continues
• test added to make sure cases other than 100 continue are treated correctly

How to test

• If possible use a proxy that adds a response (ideally not 100 continue)
• check the automated test that was added
