Auto-configure Elasticsearch REST client in Spring Data
This commit auto-configures the Elasticsearch REST client support as a template for Spring Data Elasticsearch. As of this commit, using the transport client is still possible but developers should migrate. This commit also removes the deprecated annotation on the Elasticsearch auto-configuration for the transport client, since this deprecation notice is already present on the configuration property. Closes gh-17024 Closes gh-16542
