In python 3.7, async is now a keyword, so this throws a syntax error:
File "/usr/lib64/python3.7/site-packages/libvirtaio.py", line 49
from asyncio import async as ensure_future
^
SyntaxError: invalid syntax
Switch to getattr trickery to accomplish the same goal

If we don't care about python3 < 3.4.4 compat, we can just do
from asyncio import ensure_future
