panic when a CSI-driver supports the new ControllerServer.GetSnapshot RPC

[nixpanic]

What happened:
While adding the new ControllerService.GetSnapshot RPC with kubernetes-csi/csi-driver-host-path#606, the tests fail due to a panic.

The external-provisioner panics when a CSI-driver supports the GetSnapshot RPC. Commit 4213fcf resolves this, because csi-lib-utils v0.21 contains a fix for the crash (kubernetes-csi/csi-lib-utils#188).

What you expected to happen:
No panic.

How to reproduce it:
Pass a new value for an enumeration in the CSI-drivers GetCapabilities() reply.

Anything else we need to know?:
Fix has been merged in the master branch, a new release would be most welcome.

Environment:

• Driver version: csi-driver-hostpath (Add ControllerServer.GetSnapshot CSI procedure csi-driver-host-path#606)
• Kubernetes version (use kubectl version): any

Hi Jan, you created most recent releases. Could you create an updated external-provisioner soonish?

Thanks!

This has been addressed with the v5.3.0 release (from yesterday)!
