change client type for supporting fake client to test

[hikariwo]

What this PR does / why we need it:

The origin type *clientset.Clientset is a subclass of clientset.Interface and *clientset.Clientset is not supported to use a fake client to test.It may cause further development more hard. So I suppose to modify it to an Interface type,for further testing and development.

	type Kubeclient struct {
	// clientset
	clientset *clientset.Clientset
