SplitHTTP: Rename three options & Reduce server defaults (#3611)

Browse source 
* maxUploadSize -> scMaxEachPostBytes, default is 1MB on both sides (was 2MB on the server)
* minUploadIntervalMs -> scMinPostsIntervalMs, default is 30ms on the client (no server support for now)
* maxConcurrentUploads -> scMaxConcurrentPosts, default is 100 on both sides (was 200 on the server)
