VSAN policy support for storage volume provisioning inside kubernetes
The vsphere users will have the ability to specify custom Virtual SAN Storage Capabilities during dynamic volume provisioning. You can now define storage requirements, such as performance and availability, in the form of storage capabilities during dynamic volume provisioning. The storage capability requirements are converted into a Virtual SAN policy which are then pushed down to the Virtual SAN layer when a storage volume (virtual disk) is being created. The virtual disk is distributed across the Virtual SAN datastore to meet the requirements.
For example, User creates a storage class with VSAN storage capabilities:
> kind: StorageClass
> apiVersion: storage.k8s.io/v1beta1
> metadata:
> name: slow
> provisioner: kubernetes.io/vsphere-volume
> parameters:
> hostFailuresToTolerate: "2"
> diskStripes: "1"
> cacheReservation: "20"
> datastore: VSANDatastore
The vSphere Cloud provider provisions a virtual disk (VMDK) on VSAN with the policy configured to the disk.
When you know storage requirements of your application that is being deployed on a container, you can specify these storage capabilities when you create a storage class inside Kubernetes.

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

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:
