This updates the Elasticsearch and Kibana charts to deploy version 7.1.0. This move required significant changes to both charts, including: changing elasticsearch masters to a statefulset to utilize reliable dns names for the discovery process, config updates to reflect deprecated/updated/removed values, use the kibana saved objects api for managing index patterns and setting the default index, and updating the elasticsearch entrypoint scripts to reflect the use of elastic-keystore for storing s3 credentials instead of defining them in the configuration file Change-Id: I270d905f266fc15492e47d8376714ba80603e66d Signed-off-by: Steve Wilkerson <sw5822@att.com>
