AWS Request Authenticator

Build a utility that makes authenticated HTTP requests to AWS services with proper payload handling. The utility should handle different types of request bodies and ensure they are correctly signed using AWS Signature Version 4.

Requirements

Your implementation should provide a function that:

1. Makes authenticated GET and POST requests to AWS Elasticsearch Service endpoints
2. Properly handles empty request bodies (typical for GET requests)
3. Correctly processes string request bodies (JSON data as strings)
4. Correctly processes bytes request bodies (binary data)
5. Uses AWS credentials to sign requests with proper payload hashing

The function should accept AWS credentials, endpoint information, HTTP method, and optional body data, then return the HTTP response.

Test Cases

• Making a GET request with no body to an AWS ES endpoint returns a successful response @test
• Making a POST request with an empty string body to an AWS ES endpoint includes correct content hash @test
• Making a POST request with JSON string body '{"query": "test"}' includes correct content hash @test
• Making a POST request with bytes body b'{"data": "binary"}' includes correct content hash @test
