Distribute AMI to other regions

[tomuben]

Background

Currently the AMI image is only available in the AWS region where the release runs. However, to facilitate usage, we should copy it to other regions so that user can find the image easily.

Boto3 provides a method to copy an AMI: see here.

Acceptance Criteria

• Extend the release process so that the AMI is automatically copied to other AWS regions.
  • The specific regions need to be defined, but should easily extendable.
  • Use the config to specify the region list
