Make HTTP connections start in IDLE stage, avoiding delays and error messages (#2268)
* Make all new connections start in IDLE stage, and switch to REQUEST stage only once any bytes are received from client. This makes new connections without any request obey keepalive timeout rather than request timeout like they currently do.

* Revert typo

* Remove request timeout endpoint test which is no longer working (still tested by mocking). Fix mock timeout test setup.
