Description
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.
