Amazon Elasticsearch Service is now Amazon OpenSearch Service; adds support for OpenSearch 1.0

Amazon Elasticsearch Service has a new name: Amazon OpenSearch Service. This change, which was previously announced here, coincides with the addition of support for OpenSearch 1.0. You can now run and scale both OpenSearch and Elasticsearch (until version 7.10) clusters on Amazon OpenSearch Service and get all of the same benefits you have enjoyed so far from Amazon Elasticsearch Service.
