[sunbeam] Juju 3.2 stable release break

Morning

The Juju project popped a new stable release of the 3.2 series we currently use for Sunbeam; this has created a problem with the mysql-k8s charm that we rely on for Sunbeam deployment and as such any new deployments will fail.

The team is focussed on resolving this ASAP as this is breaking all of our check/gates right now as well.

Regards

James
