how can i get labels on boot disk when gcp batch to create vm/instance template/boot disk

[breathe]

I create batch tasks with carefully  chosen labels to track and monitor costs.

I'm using python `google.cloud.batch_v1` to create my batch jobs and I've tried setting the labels field throughout the protobuf structure associated with creating the batch job.

The labels field has been set on:

- batch_v1.Runnable

- batch_v1.AllocationPolicy

- batch_v1.Job

This gets my labels set on the instances -- which is good, but not on the boot disk attached to the instance.  Any idea how this can be fixed?  It would certainly be nice if google batch would propogate through the labels set on the job to literally everything it creates -- however ... definitely doesn't do that on its own and seems to create some resources that don't have a way to be labeled at all ...
