Support python3 asyncio

[OrenHadaya]

Hi,
Is there a plan to support native python3 asyncio?
If adding asyncio support is not in the planed, would you consider marge it if i'll add this support?

thanks
Oren

@OrenHadaya : I have no plans to add support for asyncio. It will be great if you can help to implement this feature. Please add in your changes from the dev-1.1.x branch. Thanks.

Given that all versions of Python pre-3.5 (and including 3.5) are now EOL, I think it is safe to start using async/await syntax and require a Python version that accepts that.
