Comment 1 for bug 1770143

In nova, we recently migrated from the nova-consoleauth service backend to the database backend for console token authorization storage and thus the layout for running console proxies changed from global => per cell. So the console proxies need to consume the cell config to obtain vnc/spice/serial settings instead of the global nova.conf.

Patch [1] aimed to move vnc/spice/serial settings from global nova.conf => cell nova.conf for that reason *BUT* it looks like what I missed is that the nova-cpu.conf begins its life as a copy of the global nova.conf:

  https://github.com/openstack-dev/devstack/blob/master/lib/nova#L905

so that's why vnc/spice/serial settings disappeared from nova-cpu.conf unintended.

I'll come up with a fix for that.
