Describe the solution you'd like

When the value in a key/value pair is a slice like []*v1.Pod, klog currently formats the slice with the fallback fmt.Sprintf("%+v", ...) which then results in a list of pointer values ([0xc000dce900]) which is often not useful. I would find it more useful to get a dump of the objects that are pointed to.

There are probably other cases like this, but list of objects is the one I have seen myself a few times.
