Describe the feature you'd like to have

Currently, NFS export name is generated by ComposeCSIID() and the generated name is a long alphanumeric string. We hope we can specify a meaningful name for a NFS export.

What is the value to the end user? (why is it a priority?)

No priority, but I think it's good to have. Users can specify a simple and meaningful NFS export name as they want and it would be more convenient for users to manage NFS exports.

How will we know we have a good solution? (acceptance criteria)

I know that we can pass parameters in StorageClass to CSI drivers. However, specifying NFS export name in StorageClass seems not a good idea. Not sure if it's possible to pass PVC name to CSI driver?
