import GatewayConnector fails with no event loop

[vdytyniak-exos]

I am trying to import Gateway in a separate thread and it fails with:

Traceback (most recent call last):
  File "<frozen importlib._bootstrap_external>", line 883, in exec_module
  File "<frozen importlib._bootstrap>", line 241, in _call_with_frames_removed

    raise RuntimeError('There is no current event loop in thread %r.'
RuntimeError: There is no current event loop in thread 'AnyIO worker thread'.

Issue related to GatewayConnector initialisation:

class GatewayConnector(Connector):
    _executor = ThreadPoolExecutor(2)
    _resolver = netutil.ExecutorResolver(close_executor=False, executor=_executor)
    ...

ExecutorResolver tries to IOLoop.current() and fails.

Is it possible to release the fix and don't call IOLoop.current() on import?
