Request for more docker image testing prior to upload

**Summary**

Based on failures caused by unsuitable docker images being created and stored for use in future builds, I propose that additional testing be performed on docker images that we build prior to upload.

**Details**

As detailed [here](https://github.com/adoptium/infrastructure/issues/3183), our current system is capable of generating images which cannot subsequently be used to build OpenJDK.

I propose we identify testing that can identify problems prior to upload, to avoid this happening in the future. One option is to attempt to build+test OpenJDK in a generated image, with the success of these actions gating the upload. Other options likely exist also. This issue is to cover discussion of the concept, options available, and the eventual implementation.

Start with the centos7_docker_image_updater Jenkins job and the related issue 3183 to understand how generated images are currently validated and uploaded. Done means agreeing on and implementing a pre-upload test gate that prevents unsuitable images from being stored.
