kola: add KubeVirt platform support

Add KubeVirt as a new kola platform for running tests on VMs
managed by KubeVirt/OpenShift Virtualization. This includes:

- KubeVirt API client for creating/managing VMs via container disks
- SSH access via WebSocket-based port forwarding
- Cloud-init support for both ConfigDrive and NoCloud transports
- Metadata tests for afterburn integration (configdrive + nocloud)
- CI workflow with Kind cluster, KubeVirt, and kola test execution
- Vendor dependencies for kubevirt.io/api v1.8.0
