If the Infrastructure.Status.ControlPlaneTopology is set to 'External', the console-operator will pass this information via the console-config.yaml to the console. Console pod will get re-deployed and will store the topology mode information as a SERVER_FLAG. Based on that value we need to suspend these notifications:

• cluster upgrade notifications
• new channel available notifications

For these we will need to check `ControlPlaneTopology`, if it's set to 'External' and also check if the user can edit cluster version(either by creating a hook or an RBAC call, eg. `canEditClusterVersion`)
