Comment 2 for bug 1697693

After talking with Peter about this bug, we identified that https://github.com/openstack/charm-nova-cloud-controller/blob/master/hooks/nova_cc_hooks.py#L1141 is being wrongly evaluated as 'None' (string) instead of None, therefore, the resource was being installed even if console-access-protocol has been set to None (as indicated by the configuration).

We have to fix this.
