> 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.
