Subject: [PATCH] Add Liveness Probe to Kibana Deployment

This change adds a liveness probe to the Kibana deployment spec.
If multiple kibana replicas are deployed simultaniously they race
to update the .kibana index in Elasticsearch, which sometimes
results in a pod to stall without starting it's http server.
