list: Recognize UBI8 as Toolbox image & split tracked labels

UBI[0] does not have the recommend Toolbox labels used to track whether
an image/container is truly a toolbox image/container. Thankfully, they
have a number of labels to choose from that we can use to identify the
image. The "com.redhat.component=ubi8-container" seems to be ideal.

The approach of using the UBI8 label introduces one problem though. If
we were to use only one set of labels for both images and containers,
containers created with Podman and not Toolbox from UBI8 would also be
marked as toolbox containers. This is not desired and therefore there
are now two sets of labels. Ones for images where the new label has been
added and other for containers that stays the same.
