- Extend cache configs to be able to work in stanalone mode as well as
  in cluster mode in kubernetes.
- Expose the parameters to enable or disable the feature.
- to make it work in standalone mode autodiscovery config will take care , and
  to run it on kubernetes enable the kubernetes option and provide the
  service name property.
