how to set the stemcell default cpi upload location

[l-dimitrov]

Hi Team, I am faced with the following problem. We have a regional restriction in our setup and I cannot seem to setup the cpi to upload the stemcell image to any other location / region than the default (us) Here is a part of the task's debug log:

so not sure where to set this Location:"", LocationType:""
we are using:
"name": "bosh-google-cpi",
"version": "46.0.0"
In the couud_config we set zone and VM's are being deployed in the correct region but the upload-stemcell command fails as it tries to go to default us location

This doesn't seem to be supported at the moment. We will be happy to review a pr for this.
