Opensearch-perl

Still no opensearch-perl, what do we need to get this going? Looks like the elasticsearch-perl client was unaffected by the “product” checks in other clients. Will probably need to think of a new namespace as Search::OpenSearch is already taken (by support for Amazon/A9’s previous OpenSearch) and ElasticSearch’s libraries live under the Search::Elasticsearch namespace

Is there something preventing people from using elasticsearch-perl to access OpenSearch?
