(Tornado) Convert a callback-based async function to a coroutine, configuring the position/keyword the callback is expected. This can be used, for example, to convert the callback-based interface of the pika.TornadoConnection to a coroutine-based one, which is the standard async pattern suggested by Tornado nowadays.
from functools import wraps
from tornado.concurrent import return_future
class CoroutineMaker(object):
""" Convert a callback-based async function to a coroutine.
The Tornado utility gen.Task is quite useful to convert callback-based
async functions to coroutines, but has an important drawback: it expects
the callback to be passed to the function in a keyword parameter
