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.
