##### SUMMARY

We are running `ansible-test coverage` from the devel branch of Ansible on the `community.kubernetes` collection. It seems like sometime between yesterday morning and today, something in Ansible changed that is causing the error:

```
'Namespace' object has no attribute 'remote_endpoint'
```

See: https://github.com/ansible-collections/community.kubernetes/runs/1025104583?check_suite_focus=true#step:6:17
