This increases the specificity of the RemoveDuplicates strategy by removing pods which not only have the same owner, but who also must have the same list of container images. This also adds a parameter, `ExcludeOwnerKinds` to the RemoveDuplicates strategy which accepts a list of Kinds. If a pod has any of these Kinds as an owner, that pod is not considered for eviction.
