Elasticsearch: Update client and data pod deps

This updates the Elasticsearch client and data pod dependencies
to allow for sequential bring up of the cluster components. As
we want the order to be master->client->data, we add the discovery
service endpoint as a dependency for the client pods and add both
the discovery and client service endpoints as dependencies for
the data pods
