Paralell pushing to multiple registries

[dragonchaser]

With dockerhubs move to strict rate-limiting when pulling images, deploying container-based systems can be a struggle. Therefore I propose adapting the pipelines to push to multiple repositories, namely ghcr.io (github) and quay.io (redhat) to give the users a choice where to pull from. This would make setting up a cache registry obsolete in most cases. Also I suggest to pick one of the two proposed registries as a default in the documentation.

Thanks for informing us, I am going to make an internal fixme note in the container documentation with a link to this issue to track progress.
