Comment 2 for bug 2072311

What's the expected upgrade pattern for refreshing charms to the next release channel and actually doing the workload upgrade?

```
juju refresh X --channel zed/stable
juju config X openstack-origin=cloud:jammy-zed
juju refresh Y --channel zed/stable
juju config Y openstack-origin=cloud:jammy-zed
juju refresh Z --channel zed/stable
juju config Z openstack-origin=cloud:jammy-zed
```

vs

```
juju refresh X --channel zed/stable
juju refresh Y --channel zed/stable
juju refresh Z --channel zed/stable
juju config X openstack-origin=cloud:jammy-zed
juju config Y openstack-origin=cloud:jammy-zed
juju config Z openstack-origin=cloud:jammy-zed
```

I just want to be clear on definitions here, since upgrading can refer to upgrading the charm code (via juju refresh) or upgrading the workload (via updating openstack-origin).
