Support structured metadata in loki output

[truongnht]

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

Loki has support for structured metadata, and with fluent-bit 3.1, it is already possible to send to Loki output with structured metadata (see ref) which helps in capturing high cardinality data.

Describe the solution you'd like

One possible solution is to extend clusterOutput.spec.loki object with optional structuredMetadata property, which should have same structure as labels.

Hi, I would like to contribute if the issue is still open. And additional context on what needs to be implemented would help

Hi @likhith1208 it looks like it has been resolved in #1579. Thanks anyway.

But you can still check the above pull request to learn how to implement a feature request like this.

Thanks.
