Update the ssh-proxy-public service resource.

This is to address cloudfoundry-incubator#1509
This is relevant only for deployments that do not use the nginx ingress-controller.
The proposal is to ppdate the ssh-proxy-public service resource to match the scheduler pods in kubecf with the correct label.
The scheduler pods in 2.5.8 have the following labels app.kubernetes.io/component=scheduler
So the spec.selector having a value of app.kubernetes.io/component: ssh-proxy matches nothing.
