feat(packer) migrate all resources to eastus2 (#561)

Follow up of #560 

Ref.
jenkins-infra/helpdesk#3818 (comment)

This PR ensures that all the packer resources defined in the new
subscription (and only these) are migrated to US East 2 to solve errors
found in jenkins-infra/packer-images#959


Expecting 23 resources to be re-created:
- 4 RGs on the 6 are in us east today
- 4 role assignements (as the 4 RGs changed)
- 3 galleries
- 12 images (4 per gallery
