Subject: [PATCH] WIP: Compile helios in a canister (#1)

* Use stable Rust instead

* Vendor `ic-http` from `bitcoin-canister`

* config: Replace `reqwest` with `ic-http`

* Replace most of `ethers` with `ethers-core`

* consensus: replace `reqwest` with `ic-http`

* client: replace `ethers` with `ethers-core`

* client: Replace `gloo-timers` and `wasm-bindgen-futures` with `ic-cdk`

* Remove tokio::task::spawn_blocking

* remove ic-http/example_canister

* use ic-cdk instead of wasm-timer

+
+`ic-http` offers a simplified API to make HTTP outcalls on the Internet Computer with an extra convenience of mocking them in tests.
+
+## References
+
+- [Integrations](https://internetcomputer.org/docs/current/developer-docs/integrations/)
+- [HTTPS Outcalls](https://internetcomputer.org/docs/current/developer-docs/integrations/http_requests/)
+- [IC method http_request](https://internetcomputer.org/docs/current/references/ic-interface-spec#ic-http_request)
+- [Transformation Function](https://internetcomputer.org/docs/current/developer-docs/integrations/http_requests/http_requests-how-it-works#transformation-function)
+
+## Getting Started
+
+Usage:
+- Add `ic-http` to your `Cargo.toml`
+- Create a canister
+- Build a request using the `ic_http::create_request`
+  - If necessary, provide a transform function
+- Make an HTTP request using `ic_http::http_request`
+- Test with mock data by using `ic_http::mock::mock`, `ic_http::mock::mock_err`, etc.
+
+Canister:
+
+```rust
+/// Apply a transform function to the HTTP response.
+#[ic_cdk_macros::query]
+fn transform(raw: TransformArgs) -> HttpResponse {
+    let mut response = HttpResponse {
+        status: raw.response.status.clone(),
+        ..Default::default()
+    };
+    if response.status == 200 {
+        let original = parse_json(raw.response.body);
+
+        // Extract the author from the JSON response.
+        print(&format!("Before transform: {:?}", original.to_string()));
+        let transformed = original.get("author").cloned().unwrap_or_default();
+        print(&format!("After transform: {:?}", transformed.to_string()));
+
+        response.body = transformed.to_string().into_bytes();
+    } else {
+        print(&format!("Transform error: err = {:?}", raw));
+    }
+    response
+}
+
+/// Create a request to the dummyjson.com API.
+fn build_request() -> CanisterHttpRequestArgument {
+    ic_http::create_request()
+        .get("https://dummyjson.com/quotes/1")

+            value: "ic-http-example-canister".to_string(),
+        })
+        .transform_func(transform, vec![])
+        .build()
+}
+
+/// Fetch a quote from the dummyjson.com API.
+#[ic_cdk_macros::update]
+async fn fetch() -> String {
+    let request = build_request();
+    let result = ic_http::http_request(request).await;
+
+    match result {
+        Ok((response,)) => {
+            let body = String::from_utf8(response.body).unwrap();
+            format!("Response: {:?}", body)
+        }
+        Err((code, msg)) => {
+            format!("Error: {:?} {:?}", code, msg)
+        }
+    }
+}
+```
+
+Test:
+
+```rust
+#[tokio::test]
+async fn test_http_request_transform_body() {
+    // Arrange
+    let request = build_request();
+    let mock_response = ic_http::create_response()
+        .status(200)
+        .body(
+            r#"{
+                "id": 1,
+                "quote": "Life isn’t about getting and having, it’s about giving and being.",
+                "author": "Kevin Kruse"
+        }"#,
+        )
+        .build();
+    ic_http::mock::mock(request.clone(), mock_response);
+
+    // Act
+    let (response,) = ic_http::http_request(request.clone()).await.unwrap();
+
+    // Assert
+    assert_eq!(
+        String::from_utf8(response.body).unwrap(),
+        r#""Kevin Kruse""#.to_string()
+    );
+    assert_eq!(ic_http::mock::times_called(request), 1);
+}
+```
+
+## Examples
+
+- Simple canister [here](./example_canister/)
+- Some API tests [here](./tests/api.rs)
+
+## Testing
+
+```bash
+# Crate tests.
+$ cargo test
