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.

Sanic is a **Python 3.7+** web server and web framework that's written to go fast. It allows the usage of the ``async/await`` syntax added in Python 3.5, which makes your code non-blocking and speedy.

Sanic is also ASGI compliant, so you can deploy it with an `alternative ASGI webserver <https://sanic.readthedocs.io/en/latest/sanic/deploying.html#running-via-asgi>`_.

`Source code on GitHub <https://github.com/sanic-org/sanic/>`_ | `Help and discussion board <https://community.sanicframework.org/>`_ | `User Guide <https://sanicframework.org>`_ | `Chat on Discord <https://discord.gg/FARQzAEMAA>`_

The project is maintained by the community, for the community. **Contributions are welcome!**

The goal of the project is to provide a simple way to get up and running a highly performant HTTP server that is easy to build, to expand, and ultimately to scale.

Sponsor
-------

Check out `open collective <https://opencollective.com/sanic-org>`_ to learn more about helping to fund Sanic.

Installation
------------

``pip3 install sanic``

    Sanic makes use of ``uvloop`` and ``ujson`` to help with performance. If you do not want to use those packages, simply add an environmental variable ``SANIC_NO_UVLOOP=true`` or ``SANIC_NO_UJSON=true`` at install time.

    .. code:: shell

       $ export SANIC_NO_UVLOOP=true
       $ export SANIC_NO_UJSON=true
       $ pip3 install --no-binary :all: sanic


.. note::

  If you are running on a clean install of Fedora 28 or above, please make sure you have the ``redhat-rpm-config`` package installed in case if you want to
  use ``sanic`` with ``ujson`` dependency.

.. note::

  Windows support is currently "experimental" and on a best-effort basis. Multiple workers are also not currently supported on Windows (see `Issue #1517 <https://github.com/sanic-org/sanic/issues/1517>`_), but setting ``workers=1`` should launch the server successfully.

Hello World Example
-------------------

.. code:: python

    from sanic import Sanic
    from sanic.response import json

    app = Sanic("My Hello, world app")

    @app.route('/')
    async def test(request):
        return json({'hello': 'world'})

    if __name__ == '__main__':
        app.run()

Sanic can now be easily run using ``sanic hello.app``.

.. code::

    [2018-12-30 11:37:41 +0200] [13564] [INFO] Goin' Fast @ http://127.0.0.1:8000
    [2018-12-30 11:37:41 +0200] [13564] [INFO] Starting worker [13564]

And, we can verify it is working: ``curl localhost:8000 -i``

.. code::

    HTTP/1.1 200 OK
    Connection: keep-alive
    Keep-Alive: 5
    Content-Length: 17
    Content-Type: application/json

    {"hello":"world"}

**Now, let's go build something fast!**

Minimum Python version is 3.7. If you need Python 3.6 support, please use v20.12LTS.
