test_shutdown_with_invalid_host fails

[SwooshyCueb]

The test test_control_plane.TestControlPlane.test_shutdown_with_invalid_host fails on tip of main. It also takes a very very long time to run. I can consistently reproduce this test failure in my Ubuntu 22.04 container with postgres, though the output sometimes differs.

Here's a snippet from the test output:

======================================================================
FAIL: test_shutdown_with_invalid_host (irods.test.test_control_plane.TestControlPlane)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/var/lib/irods/scripts/irods/test/test_control_plane.py", line 208, in test_shutdown_with_invalid_host
    self.assertTrue(({'failed_to_connect': 'tcp://invalid_host:1248'} in host_responses) or ({'response_message_is_empty_from': 'tcp://invalid_host:1248'} in host_responses))
AssertionError: False is not true

Possibly similar to https://github.com/irods/irods/issues/7389, although it seems I only observed the failure on Debian...

Linking to https://github.com/irods/irods/issues/7521 as well. Something funny about this test suite.
