Remove nova-consoleauth

The nova-consoleauth service was deprecated during the Rocky release [1]
and has not been necessary since unless you're using cells v1. As Kolla
has never supported cells v1, which is finally being removed during
Train [2], we can get ahead of the curve and stop deploying
nova-consoleauth immediately.
