Provide a more ideal example for scheduler extender policy.

We now use default predicates/priorities if they are unspecified in the policy config (kubernetes/kubernetes#59363). The other example in ./scheduler-policy-config.json shows how to use priorities and predicates. Let's use this example to show how to use extenders. When you are using extenders you don't necessarily want to mess with priorities and predicates (kubernetes/kubernetes#45188). Also remove duplicate file.
