hetzner cloud provider does not implement FindVPCInfo at thi

Error message

hetzner cloud provider does not implement FindVPCInfo at this time

What it means

FindVPCInfo on the Hetzner cloud implementation is a stub: it unconditionally returns an error because VPC/network discovery has not been implemented for Hetzner. Any code path that asks the Hetzner cloud for VPC info will always fail here regardless of input.

Solutions

1. Avoid kops operations that require VPC discovery on Hetzner clusters
2. Contribute an implementation of FindVPCInfo for the Hetzner provider
3. Supply network configuration explicitly so VPC lookup is not needed
