OpenSearch data source supports Private Data Source Connect (PDC)

Version 2.21.0 of the Grafana OpenSearch plugin introduces support for private data source connect (PDC).

PDC is a way for you to establish a private, secured connection between a Grafana Cloud instance, or stack, and data sources secured within a private network. This makes it possible to take advantage of the convenience and power of Grafana Cloud, even if your OpenSearch cluster is hosted in a Virtual Private Cloud (VPC) or another private network.
