clientset interface functions deprecated

Since we mark functions of clientset interface such as Core(), Autoscaling().... as deprecated, should we change all the calling of Core() to specific version like CoreV1() ... ?

https://github.com/kubernetes/kubernetes/blob/master/pkg/client/clientset_generated/clientset/clientset.go

Start by reading pkg/client/clientset_generated/clientset/clientset.go and review the deprecated Core(), Autoscaling(), and related interface functions. Search the repository for calls to those functions and determine whether each should use a specific versioned accessor such as CoreV1(). Done means the applicable callers consistently use version-specific functions and the relevant checks pass.
