Code Issues Proposed changes

Add intel-power and power-metrics to list of platform namespace

Browse Source 
The intel-power and power-metrics namespace are used by
Kubernetes Power Manager [1] and  Power Metrics [2] StarlingX
platform applications. Therefore, their pods have to run at platform
cores.

[1] https://opendev.org/starlingx/app-kubernetes-power-manager
[2] https://opendev.org/starlingx/app-power-metrics

Test Plan:
PASS: Verify if the pods are running at the platform cores

Story: 2010773
Task: 48414

Depends-On: https://review.opendev.org/c/starlingx/integ/+/887743
