  - Added user-owned fields in `ResourceClaim` to specify resource requirements against each device capacity.
  - Added scheduler-owned field in `ResourceClaim.Status` to specify how much device capacity is reserved for a specific request.
  - Added an additional identifier to `ResourceClaim.Status` for the device supports multiple allocations.
