Comment 2 for bug 1937263

Yes, the action exist due to the inherent inaccuracy of charm readiness vs. payload readiness ref bug 1854518. And this also affects the Nova API calls required to create the SSH keys.

To fully resolve this class of issues we need a outside view of the model with something like a governor charm. This is not possible to resolve within the current APIs and guarantees provided by Juju.

As such I'll triage this as a feature request.
