Code Issues Proposed changes

Add sriov-fec-system namespace to the platform infra list in kubelet

Browse Source 
Currently the pods installed in the sriov-fec-operator namespace run
on application cores. The sriov-fec-operator App is seen
as a platform app and therefore its pods need to run on platform
cores.

Accordingly, add the sriov-fec-system namespace to the list of
platform namespaces in kubelet.

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