DeprecationWarning: The event_loop fixture provided by pytest-asyncio has been redefined

[rambo]

Replacing the event_loop fixture with a custom implementation is deprecated
and will lead to errors in the future.
If you want to request an asyncio event loop with a scope other than function
scope, use the "scope" argument to the asyncio mark when marking the tests.
If you want to return different types of event loops, use the event_loop_policy
fixture.

We have some weird side-effects so doing this is far from simple, a lot of the tests need to be re-written. We also can't update dependencies before that is done.
