Public bug reported:

If we config instance_name_template differently in controller node and
compute node will lead to VM not be deleted in the compute node, but the
instance is deleted in the OpenStack.

The reason of the issue are:
When boot instance, instance's name generated on controller node using controller's instance_name_template config and  is passed to nova-comute and used to boot a VM as VM's name.
But When delete instance, instance's name do not pass from controller node to compute node, the instance's name is generated on compute node using compute's instance_name_template config, so the nova-compute will not find the VM to delete when compute node try to delete the VM using the instance name genenrated on compute node.

The nova should use instance_name_template either on controller node or
compute node, and should be consistent.
