##### SUMMARY

In the Kubernetes collection's CI tests, the sanity check, which uses `ansible-test sanity --docker -v --color --python 3.6`, started failing with the following error:

```
ERROR: Command "importer.py" returned exit status 1.
>>> Standard Error
Traceback (most recent call last):
  File "/root/ansible/ansible_collections/community/kubernetes/tests/output/.tmp/sanity/import/minimal-py36/bin/importer.py", line 447, in <module>
    main()

  File "/root/ansible/lib/ansible/constants.py", line 12, in <module>
    from jinja2 import Template
ModuleNotFoundError: No module named 'jinja2'
```

Nothing in the collection has changed in the past week, and no runs failed until this morning's CI run, so it seems something committed to ansible/ansible `devel` has caused this failure.
