- for objects in S3 - match filenames starting with Composer-Test
- for keys use the new Composer-Test-Key- prefix (for consistency)
- for VM names use Composer-Test-VM- prefix instead of ami id
Not all parts of the script has been switched from awscli to ansible yet,
because the ansible aws modules do not support importing s3 object as snapshots.

Workaround using the image_location parameter of the ec2_ami ansible module
would mean adding extra code for generating AMI manifest with pre-signed
URLs.
