ignore-nested-functions should work with coroutines

[amin-nejad]

Describe the feature you'd like

I'd like ignore-nested-functions to work with coroutines (i.e. async def). However if either function is actually a coroutine, it does not work

Is your feature request related to a problem?

I'm frustrated when I have to add docstrings to unimportant functions and I can't avoid it just because of how they are defined i.e. there is nothing materially different between a function and coroutine when it comes to docstrings and their necessity (or lack thereof)
