Add optional instructions to deploy Kibana

Your project is amazing for setting up elasticsearch on kubernetes, but it would be great to have the yaml files for setting up kibana also. Could this be added to the project?

I'm open to review PRs that add that functionality as an opt-in, meaning disabled by default but easily enabled by any user interested in having it.
