Additional documentation e.g., KEPs (Kubernetes Enhancement Proposals), usage docs, etc.:

Containers in recommendation can be different from recommendations in pod:

- A new container can be added to a pod. At first there will be no
  recommendation for the container
- A container can be removed from pod. For some time recommendation will contain
  recommendation for the old container
- Container can be renamed. Then there will be recommendation for container
  under its old name.

Add tests for what VPA does in those situations.

Add tests for what VPA does in those situations, when limit range exists.

I ran tests in my cluster (whole admission-controller suite, including those I add in this PR) and they passed.
