Feat: record origin of client requests in metrics

[sfauvel]

Content

This PR includes support for a new HTTP header in the aggregator REST API which allows recording the origin of requests.

The aggregator can set a list of authorized origin tags in its configuration. The default list contains EXPLORER, BENCHMARK, CI and NA which can be extended with additional tags.

The clients have also been updated to be able to provide the origin tag parameter.

---

Rust example using the mithril-client crate:

    let client =
        ClientBuilder::aggregator(&args.aggregator_endpoint, &args.genesis_verification_key)
            .with_origin_tag(Some("EXAMPLE".to_string()))
            .build()?;

---

Javascript example using the mithril-client-wasm library:

  let client_options = {
    origin_tag: "EXAMPLE"
  };
  let client = new MithrilClient(aggregator_endpoint, genesis_verification_key, client_options);

---

Client CLI command example:

mithril-client -- --origin-tag EXAMPLE cardano-db snapshot list

• The 'with_origin_tag' middleware is passed 'dependency_manager' here instead of 'router_state' as used in similar routes; please verify this is intentional.

• Consider using 'router_state' consistently for the 'with_origin_tag' middleware. Verify if passing 'dependency_manager' here is intentional compared to other endpoints that use 'router_state'.
