feat: Add kube_node_status_images metric

[hausertt]

What this PR does / why we need it:

Collects metrics of container images present on the node. With the recent growth in image sizes, especially for self-hosted AI solutions, monitoring these metrics can help fix node-pressure.

How does this change affect the cardinality of KSM: (increases, decreases or does not change cardinality)

Increases one metric: kube_node_status_images

This is an interesting idea, though I have concerns about the number of metrics exposed.
Effectively this is #nodes * #images
A rough calculation: In a cluster with 100 nodes, 50 pods scheduled in each node and the image rention being roughly 4 versions, this would mean 2000 additional series being reported.

I'm interested in thoughts from others but would at least say this should be an opt-in metric.
