Investigate if mizar network pods need to be privileged

[vinaykul]

Currently mizar deployment in k8s cluster requires privileged containers. https://github.com/CentaurusInfra/mizar/blob/dev-next/etc/deploy/deploy.mizar.components.yaml

We should investigate to see if we can do away with privileged container requirement and use a minimum set of capabilities instead by using securityContext.capabilities.add .
