Hi, is it possible to add support for sending structured metadata in addition to labels?

https://grafana.com/docs/loki/latest/get-started/labels/structured-metadata/

It's an experimental feature, but promtail already supports it and it would be nice if loki-logback-appender supported it as well.

Thanks in advance
