There were a lot of workarounds here to ensure we didn't switch to the new model (vs. the old 'nova-consoleauth' service) if users were on cells v1. These can go now, along with the old 'nova-consoleauth' service (though that's a later, separate change). Part of blueprint remove-cells-v1 Change-Id: I1b8f411b050d34e4e77e9a4f1e613135eb5f74b7 Signed-off-by: Stephen Finucane <sfinucan@redhat.com>
