Previously, the cluster-build code would recreate imagestreams, which
would drop the association of image streams to images previously
created. To avoid this, the code is updated to never delete
imagestreams, and only recreate imagestreamtags.

The tags in the status section simply serves no purpose/is misleading,
as it is not used.

This reverts commit ebdbb1fc.

Same as parent commit.

This reverts commit 5008eb4e.

The RHEL8-Cluster-Image-Builder has problems and is not ready. This
commit reverts the switch, and uses RHEL8-Image-Builder instead.
