> A vendor might need a customized scheduling policy for their devices. It
> could be scheduled based on topology, resource utilization, virtualization,
> device attribute and so on.
> We'll provide another optional interface "DevicePluginScheduler" for the
> vendor device plugin to implement. Once it's implemented, the framework will
> prefer it to the default scheduler.
> This would bring more flexibility to the framework's scheduling mechanism.
