Is this still relevant? If so, what is blocking it? Is there anything you can do to help move it forward?

I thought about this pr again and it may be better to create a new plugin to support vGPU.

Here is rough idea about this plugin:

• start vGPUServer once
• maintain a local cache of Pod/Node/vGPUDeviceInfo,
• add a predicate function to filter vGPU nodes for Pod
• add allocate/deallocate function to update vGPU info to local cache
