third party BackupItemAction cannot support the VolumePolicy in v1.14.0

[blackpiglet]

Describe the problem/challenge you have

https://github.com/vmware-tanzu/velero/blob/62c7fef8274260f6e5349197058666f01e12a60a/pkg/backup/item_backupper.go#L380-L397 Due to this logic check, the VolumePolicy is limited to the Velero CSI BIA, all the other BIA plugins cannot support the VolumePolicy, including the Velero vSphere plugin.

This is a known issue for Velero v1.14.0. The reason is the current BackupItemAction mechanism doesn't have an easy way to let the Velero pass in the VolumePolicy information into the BIA. The next patch version of v1.14 will give a way to address it.

Describe the solution you'd like

Anything else you would like to add:

Environment:

• Velero version (use velero version):
• Kubernetes version (use kubectl version):
• Kubernetes installer & version:
• Cloud provider or hardware configuration:
• OS (e.g. from /etc/os-release):
