Finalizers stop deleting a namespace after cleaning up a Hawtio instance

It apears that the finalizers are installed for cleaning up some cluster-wide resources like ConsoleLink and OAuthClient:

hawtio-operator/pkg/controller/hawtio/hawtio_controller.go

Line 261 in 1373399

    
           // Add a finalizer, that's needed to clean up cluster-wide resources, like ConsoleLink and OAuthClient

Probably the issue is that it doesn't work as originally expected and instead blocks the clean up and reinstallation in some way. Instead of removing the finalizer altogether, we can revisit and improve it to not block the clean up anymore.
