Comment 4 for bug 1991511

"the next stage of testing is to deploy the old version of the charm (that includes the workload) and then test a charm upgrade to the new version that doesn't include the workload."

I was just explaining why I was doing what I was doing. The short version is that trying to run this command fails:

```
juju deploy nginx-ingress-integrator --channel=edge --revision=29 ingress
```
