genomics API spuriously creating VM instances

[njbernstein]

Hi there

I used Cromwell to kick off a batch of jobs using this workflow

I killed the Cromwell job but the genomics api is continuing to spin up VM instances.

I can't get the operation id because when I run
gcloud --project=calico-uk-biobank alpha genomics operations list and it's up to 300MB of JSON so far...

Also in our case, there are no running ones in the webui.
