OTEL: Resource Detection Processor

[gouthamve]

Request

The resourcedetectionprocessor and k8sattributesprocessor are good ways to enrich the signals with common metadata and we should make sure the Agent supports it.

Use case

To help add the right metadata to the signals collected by the Agent.

This is slightly different from the Prometheus SD mechanism in that it produces attributes that are aligned to the defined OpenTelemetry Semantic Conventions.
