Support sync node status.images with pod

[wzshiming]

What would you like to be added?

• Support sync node status.images with pod
• Add a flag to allow kwok-controller to enable this feature.

Why is this needed?

Refinement of simulated kubelet behavior

Hi, I'm interested to contribute to this feature.

Do you have any pointers on where to start? Thank you.

[wzshiming]

My idea would be to add a template function to node template that would look like this

images:
{{ with NodeImages status.images }}
{{ YAML . 1 }}
{{ end }}

The NodeImages return will contain the status.images and the images used by the pods on this node.

Hi, @wzshiming. Is the feature independent of v1alpha2?
