Subject: [PATCH 1/2] libvirtaio: Fix compat with python 3.7
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
