Adding "Real Time KVM" support

Adding the support to run the "Real Time KVM" kernel in the compute
node(s) to reduce the network latency caused by the virtualization of
the network functions. Since the current "Real Time KVM" kernel
doesn't support physical to logical network interface mapping yet, we
need to use the real physical interface name rather than the logical
interface name for all compute interfaces in network_settings.yaml.

Also updates tests for the network settings changes and fixes a bug
where interface was being queried on the controller nics before it
interfaces were validated.
