Default configuration prevents Nova KVM hypervisors from working

[diurnalist]

We have some values in defaults.yml that need to be undone if you want to use this to deploy a KVM cloud.

nova_compute_virt_type: none
# We are not using any VNC consoles; the serialproxy is not considered a 'nova_console'
nova_console: none

These values are set to "none" to turn off some aspects of the deploy specific to a bare metal-only cloud, and should be customizable if a KVM deployment is desired.

For example, a KVM deployment may want:

nova_compute_virt_type: kvm
nova_console: novnc
