Currently, images listed on https://www.centos.org/download/aws-images/ aren't the latest ones, as there was no automation to open either PR, nor git commit to reflect newly built images.

The goal in this ticket is to just automate missing parts, and pulling from jenkins artifacts :

• https://jenkins.stream.centos.org/view/c8s%20release/job/stream8-images-ec2/
• https://jenkins.stream.centos.org/view/c9s%20release/job/stream9-images-ec2/
