[PATCH 02/14] python: avoid deprecation warning with get_event_loop

["Daniel P. Berrangé" <berrange@redhat.com>]

We need to call get_event_loop but have no way of knowing ahead
of time whether the current thread has an event loop of not. We
can handle a missing event loop, but we need to hide the warning
python will emit to avoid tripping up iotests expected output.
