How about a decorator like WithSelectors(NewListWatchFromClient(...))? All these ListOptions modifications are orthogonal to the actual ListWatch construction. ListOptions have even more fields. We don't want to add yet another constructor after this one. Decorators are more natural.

Sounds much better. Let me rewrite this function. @sttts thanks

To be inline with the naming of filtered informers (NewFilteredSharedInformerFactory), let's call it NewFilteredListWatchFromClient.

The `NewFilteredListWatchFromClient` function introduced in client-go v7.0.0 allows us to filter based on custom fields/labels, therefore we don't need our custom implementation of this functionality. The function was introduced [here](kubernetes/kubernetes#57508) Signed-off-by: Lorenzo Manacorda <lorenzo@kinvolk.io>

What this PR does / why we need it:
metav1.ListOptions support both field selector and label selector, but the current NewListWatchFromClient in client-go only support field selector.
It would be helpful to use label selector in client-go.
