Optimization of on-wire information sent to scheduler extender interfaces that are stateful

The changes are to address the issue described in https://github.com/kubernetes/kubernetes/issues/40991

```release-note
Added support to minimize sending verbose node information to scheduler extender by sending only node names and expecting extenders to cache the rest of the node information
```
