Brief Description
-----------------

The configured application-isolated type CPUs can't be used by Kubernetes Pods and CPU resources required by the Pods are still from application type CPUs.

Severity
--------
Major

Steps to Reproduce
------------------

[sysadmin@controller-0 ~(keystone_admin)]$ system host-lock controller-0
[sysadmin@controller-0 ~(keystone_admin)]$ system host-cpu-modify -f application-isolated -p0 10 controller-0
[sysadmin@controller-0 ~(keystone_admin)]$ system host-unlock controller-0

[sysadmin@controller-0 ~(keystone_admin)]$ system host-cpu-list controller-0
