Madhu Rajanna e0cc7740f6 CSI: run all containers as privileged in daemonset pods
On systems with SELinux enabled, non-privileged containers
can't access data of privileged containers. Since the socket
is exposed by privileged containers, all sidecars must be
privileged too. This is needed only for containers running
in daemonset as we are using bidirectional mounts in daemonset
