Add a Node-Exclusive ResourceSlices section to `kubectl describe node`
that displays DRA ResourceSlices assigned exclusively to the node.
Key design decisions per reviewer feedback:
1. Uses indexed field selector (spec.nodeName) for O(1) query performance
instead of fetching all slices cluster-wide. This is critical for
large clusters with thousands of ResourceSlices.
2. Shows only node-exclusive slices (where spec.NodeName == thisNode).
Does NOT show AllNodes, NodeSelector, or PerDeviceNodeSelection slices
as these could number in the thousands and aren't node-specific.
3. Aggregates by driver/pool instead of listing individual slices:
- Shows: Driver, Pool, Slices count, Devices count
- More concise and useful output
4. Caps output at 10 pools with "...and X more pools" message,
following the existing formatEndpointSlices pattern.
Example output:
Node-Exclusive ResourceSlices:
Driver Pool Slices Devices
