Is your feature request related to a problem? Please describe.

Currently, the elasticsearch exporter only supports OTLP Traces/Logs directly to Elasticsearch but not Metrics. Is that by choice? If not, I'd like to contribute to the exporter and add support for Metrics to it.

Describe the solution you'd like

The elasticsearch exporter is able to export OTel metrics using OTLP to Elasticsearch.

My apologies if I'm missing something simple, but it looks like Elasticsearch supports OTLP natively, so you can just use the otlp exporter for metrics. Is there a reason this doesn't fit your use case?
