optional auto_decompress for HttpRequestParser

[p4l1ly]

Is your feature request related to a problem?

auto_decompress can be disabled for client but unfortunately not for server.

Describe the solution you'd like

Export the API (I'm going to open a PR few minutes after filing this issue)

Describe alternatives you've considered

The feature can be hacked by setting AIOHTTP_NO_EXTENSIONS=true and

request_handler_init = web.RequestHandler.__init__

def disable_decompression(self, *args, **kwargs):
    request_handler_init(self, *args, **kwargs)
    self._request_parser._auto_decompress = False

web.RequestHandler.__init__ = disable_decompression

but that is ugly and slow.
