What This PR Does / Why We Need It

This PR adds a goframe framework adapter for Sentinel. With this adapter, developers can easily integrate Sentinel's rate limiting and circuit breaker functionalities into their goframe projects, thereby enhancing system stability and reliability.

How It Was Done

1. Implemented the SentinelMiddleware function to integrate Sentinel into the goframe framework.
2. Added the withResourceExtractor option to allow developers to customize resource extraction logic.
3. Added the WithBlockFallback option to allow developers to customize fallback logic when blocked.
4. Wrote corresponding test cases to ensure the correctness and stability of the adapter.

How to Verify It

1. go test -run ^TestSentinelMiddlewareDefault -v
2. go test -run ^TestSentineIMiddlewareExtractor -v
3. go test -run ^TestSentinelMiddlewareFallback -v
