Run test async using a wrapper for Cassandra python driver's future.
The wrapper was suggested by a user and brought forward by @fruch.
It's based on https://stackoverflow.com/a/49351069 .
Redefine pytest event_loop fixture to avoid issues with fixtures with

See https://github.com/pytest-dev/pytest-asyncio/issues/68
Convert sample test_null to async. More useful test cases will come
afterwards.
