Opensearch sink

[Willem1987]

Recently Opendistro for Elasticsearch continued as OpenSearch. This project has it's own go client.

Requesting for an Opensearch sink based on elasticsearch client using https://github.com/opensearch-project/opensearch-go . The es7 sink will work for now, but this is unsure looking forward.

Is there an update on this? We're trying to use the Elasticsearch sink itself to push to an Opensearch instance but that doesn't seem to be working We're getting the following error

{"level":"error","time":"2022-04-20T11:33:58Z","caller":"/app/pkg/sinks/elasticsearch.go:144","message":"Indexing failed: {\"error\":{\"root_cause\":[{\"type\":\"mapper_parsing_exception\",\"reason\":\"object mapping for [involvedObject.labels.istio] tried to parse field [istio] as object, but found a concrete value\"}],\"type\":\"mapper_parsing_exception\",\"reason\":\"object mapping for [involvedObject.labels.istio] tried to parse field [istio] as object, but found a concrete value\"},\"status\":400}"}

This is our configmap
