Charm does not react to changes in 'source' charm config option

[Liam Young]

Changing the charm source config option does not result in ovn being upgraded. To reproduce run the charms functional test for focal-victoria and then 'juju config ovn-dedicated-chassis source=cloud:focal-wallaby'. The charm should upgrade ovn-common and ovn-host packages but it does not.

Triage: Set bug to high. I'm guessing it doesn't support action-managed-upgrades as that's a layer-openstack-principal which I don't think is included in the charm.

It seems to be because the initial install is done via the default_install method triggered from @reactive.when_not('charm.installed') which comes from layer-openstack. From then on the charm just does no have a handler that runs install and as ajkavanagh (and Bug #1902561) note, there is no action-managed-upgrade option
