MultiKueue: Support cluster colocation for Deployment

[tenzen-y]

What would you like to be added:

I would like to schedule all Deployment Pods to the same cluster as the StatefulSet.

Why is this needed:

The current Deployment MultiKueue implementations depend on the Plain Pods as opposed to the Pod Group, which means any Pods could be potentially scheduled to any cluster.

This is obviously a limitation for MultiKueue deployment support.

Completion requirements:

This enhancement requires the following artifacts:

• Design doc
• API change
• Docs update

The artifacts should be linked in subsequent comments.
