Duplicate cluster scoped objects while listing using MultiNamespacedCache

[vinod-patil]

I am using manager client to list and get resources from cache with below option to cache objects from multiple namespaces

ctrl.Options{
   NewCache: cache.MultiNamespacedCacheBuilder([]string{"ns1", "ns2", "ns3"})
}

But whenever I list cluster scoped resources function is returning duplicate resources after combining resources from each namespace map so in my case resource count is going to be 3 * actual as I used 3 namespaces in cache builder.

Sounds like the MultiNamespaceCache needs proper handling for cluster-scoped resources. Objections to converge this issue into #1378 and close it?
