Add Elastic and/or Opensearch sink to Debezium Server [DBZ-7854]

Migrated from [DBZ-7854](https://issues.redhat.com/browse/DBZ-7854)

h1. Feature request
h2. Which use case/requirement will be addressed by the proposed feature?

I have PostgreSQL database, and I want to use Opensearch or Elastic for the fulltext search. It would be nice to add Opensearch or Elastic sink to Debezium Server. I know that I can use Kafka Connect's Connector, for example [https://github.com/Aiven-Open/opensearch-connector-for-apache-kafka,] but it involves Kafka, that increases infrastructure costs, makes architecture more complex and adds more moving parts. Sending data from PostgreSQL via Debezium Server to Opensearch looks as enough solution for my particular usecase.
