Restart device plugin pod after node policy applied

We need to restart device plugin pod after node policy applied
and all SR-IOV Network Config Daemon plugins finished. E.g.:

Generic plugin applies SR-IOV Network Node Policy and creates
VFs. That's mean we need to restart device plugin pod to found
newly created devices.
