Direzione di ricerca
Look at the existing prometheus scrape source implementation (likely in `src/sources/prometheus/scrape.rs`). Examine how http client already supports configurable headers (e.g., in `src/sinks/http.rs` or `src/http.rs`). Propose adding a similar `headers` configuration field to the prometheus scrape source and integrate it into the HTTP requests made by that source. Check the configuration schema and ensure the fields are properly validated.
