Delete a route for FastAGI requests:

        :param path: URI to answer. Ex: 'calls/start'
        :type path: String

        :Example:

        ::

            @asyncio.coroutine
            def start(request):
                print('Receive a FastAGI request')
                print(['AGI variables:', request.headers])

            fa_app = Application()
            fa_app.add_route('calls/start', start)
            fa_app.del_route('calls/start')
