feat(sdk-rs): circuit breaker and multiple endpoints

Ref CONSOLE-1605

Rust SDK

Circuit Breaker Implementation and Multiple Endpoints Support

Implementation of Circuit Breakers in Hive Console Rust SDK, you can learn more here

Breaking Changes:

Now endpoint configuration accepts multiple endpoints as an array for SupergraphFetcherBuilder and PersistedDocumentsManager.

SupergraphFetcherBuilder::default()
-    .endpoint(endpoint)
+    .add_endpoint(endpoint1)
+    .add_endpoint(endpoint2)

This change requires updating the configuration structure to accommodate multiple endpoints.

Apollo Router Plugin

• Multiple endpoints support for HiveRegistry and PersistedOperationsPlugin

Breaking Changes:

• Now there is no endpoint field in the configuration, it has been replaced with endpoints, which is an array of strings. You are not affected if you use environment variables to set the endpoint.

HiveRegistry::new(
    Some(
        HiveRegistryConfig {
-            endpoint: String::from("CDN_ENDPOINT"),
+            endpoints: vec![String::from("CDN_ENDPOINT1"), String::from("CDN_ENDPOINT2")],
    )
)

Summary of Changes

Hello @ardatan, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request significantly improves the robustness and availability of the Hive Console Rust SDK and its Apollo Router Plugin by integrating a circuit breaker pattern and enabling the use of multiple CDN endpoints. These changes allow the system to gracefully handle failures and switch to healthy endpoints, ensuring continuous operation even when some services are degraded.

Highlights

• Circuit Breaker Implementation: Introduced a circuit breaker pattern into the Hive Console Rust SDK to enhance resilience and prevent cascading failures when communicating with external services. This is applied to both usage reporting and document fetching.
• Multiple Endpoints Support (Rust SDK): The SupergraphFetcherBuilder and PersistedDocumentsManager in the Rust SDK now support configuring multiple CDN endpoints. This allows for automatic fallback to alternative endpoints if one fails, improving availability.
• Multiple Endpoints Support (Apollo Router Plugin): The HiveRegistry and PersistedOperationsPlugin in the Apollo Router Plugin have been updated to support multiple endpoints, providing similar resilience benefits for these components.
• Breaking Changes in Configuration: The endpoint configuration field has been replaced with an endpoints array for SupergraphFetcherBuilder, PersistedDocumentsManager, and HiveRegistryConfig. Existing configurations using a single endpoint string will need to be updated to an array format.

Code Review

This pull request introduces circuit breaker functionality and support for multiple endpoints to the Rust SDK and Apollo Router plugin, enhancing resilience. The changes involve breaking API updates for configuration. My review identifies critical issues with potential panics in the supergraph_fetcher due to improper error handling, and medium-severity issues in circuit_breaker.rs related to code duplication and a misleading comment.
