Adding new Kubernertes units when running with CNI not working

[simonklb]

Something needs to be done to enable CNI for new units added after initial deployment as well. It's problematic because you won't have cluster-wide CNI support which obviously will lead to inconsistencies but even worse, new units cannot even join the cluster.

Workaround I'm using atm is to manually attach the IAM role to the instance and set the cloud-provider snap option.

We're working with the Juju team to try and get this functionality included.
