Description of problem:
There is a single health probe endpoint in both API Server and Controller Manager pods for Service Catalog that covers both readiness and liveness.  The readiness functionality should be split to a dedicated probe specific for readiness to avoid unnecessary pod restarts.

Example from the API Server health probes:
        readinessProbe:
          httpGet:
            port: 6443
            path: /healthz
   .....
        livenessProbe:
          httpGet:
            port: 6443
            path: /healthz


readiness should have its own url.
