Migrate cpu relevent configuration parameters from tempest.conf to
nova_yamls file. Before cpu information about the hosts such as the cpu
topology and dedicated/shared set was pulled from tempest.conf. This
change moves the information to the nodes yaml approach [1] for
accessing host specific service information. The format of the
information can be seen below:
compute-0.redhat.local:
services:
libvirt:
container_name: nova_virtqemud
start_command: 'systemctl start tripleo_nova_virtqemud'
stop_command: 'systemctl stop tripleo_nova_virtqemud'
nova-compute:
container_name: nova_compute
config_path: '/var/lib/config-data/puppet-generated/nova_libvirt/etc/nova/nova.conf'
start_command: 'systemctl start tripleo_nova_compute'
stop_command: 'systemctl stop tripleo_nova_compute'
cpu_shared_set: 0,1
cpu_dedicated_set: 4,5,6,7
numa:
node-0:
cpus: "0-3"
node-1:
cpus: "4-7"
