Verified on my environment according to @sseago comments.

Need to --go_opt=module=github.com/vmware-tanzu/velero/pkg/plugin/generated in protoc command, and remove option go_package = "github.com/vmware-tanzu/velero/pkg/plugin/generated"; from proto files.

Rebased to main to resolve conflicts, and fixed the hack/update-*.sh files to make sure protoc generation happens before crd generation.

Updated to newer protobug/protoc-gen-go since the module option isn't supported in the ancient 1.0.0 protoc-gen-go we're currently using. This is breaking tests now, so I'll need to fix some things now. Looks like some changes to generated code may need to be reflected in the velero code that references it.

I have tested this PR with our existing OADP/OpenShift backup item action plugins. The only thing I had to do for this to work was to rebuild the image with the velero deps updated to include the code changes in this PR.

Using the new code with an old plugin image (based on incompatible velero dependencies) will result in an error like the below when trying to run a backup:

time="2022-08-29T18:53:11Z" level=error msg="backup failed" controller=backup error="rpc error: code = Unimplemented desc = unknown service v1.BackupItemAction" key=openshift-adp/bia-test logSource="pkg/controller/backup_controller.go:301"
