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
```
cc @ravigadde
node cache don't need to get all the information about every
candidate node. For huge clusters, sending full node information
of all nodes in the cluster on the wire every time a pod is scheduled
is expensive. If the scheduler is capable of caching node information
along with its capabilities, sending node name alone is sufficient.
These changes provide that optimization in a backward compatible way
- removed the inadvertent signature change of Prioritize() function
- added defensive checks as suggested
- added annotation specific test case
- updated the comments in the scheduler types
- got rid of apiVersion thats unused
- using *v1.NodeList as suggested
- backing out pod annotation update related changes made in the
1st commit
- Adjusted the comments in types.go and v1/types.go as suggested
in the code review

Alpha version of dynamic volume provisioning is removed in this release. Annotation
"volume.alpha.kubernetes.io/storage-class" does not have any special meaning. A default storage class

fixing Cassandra shutdown example to avoid data corruption
Hi,
I was playing with Cassandra example stored in the Kubernetes project and I encountered issues on shutdown (not anytime). After checking it looks like the shutdown of a node is brutal and data corruption may occur during a flush on disk. To avoid that, I'm suggesting a hook to gracefully shutdown Cassandra before stopping the container.
Here are logs of corruption after a pod delete:
