config-daemon: Restart all instances of device-plugin

[zeeke]

When the operator changes the device-plugin Spec (e.g. .Spec.NodeSelector), it may happen that there are two device plugin pods for a given node, one that is terminating, the other that is initializing. If the config-daemon executes restartDevicePluginPod() at the same time, it may kill the terminating pod, while the initializing one will run with the old dp configuration. This may cause one or more resources to not being advertised, until a manual device plugin restart occurs.

Make the config-daemon restart all the device-plugin instances it founds for its own node.
