Pillar / config used

Trying to add

              - location = /stub_status:
                  stub_status

---

Bug details

Describe the bug

The rendered seems to expect something after the first word, but if that's true for most, the stub_status command is standing alone.

Steps to reproduce the bug

Use the above YAML, and observe.

Expected behaviour

The rendering should not fail because there is no value after stub_status.

Attempts to fix the bug

Solution is to use

- location = /stub_status:
    - stub_status: 'on'

But, the 'on' is not necessary as per the nginx doc.

Additional context

Ideally, it should be added in the pillar.example so that people do not struggle...
