feat: add Sentinel RocketMQ 5.x adapter module

[oss-sentinel-ai]

Summary

This PR adds a new module spring-cloud-alibaba-sentinel-rocketmq that provides Sentinel integration for Apache RocketMQ 5.x.

Problem

The existing sentinel-rocketmq-adapter module in the Sentinel project only supports RocketMQ 4.x. With RocketMQ 5.x having a completely different API, we need a new adapter module specifically designed for RocketMQ 5.x.

Solution

Created a new Spring Boot starter module that:

• Provides SentinelProducerInterceptor for producer flow control and circuit breaking
• Provides SentinelConsumerInterceptor for consumer flow control and circuit breaking
• Uses RocketMQ 5.x hook mechanism (SendMessageHook and ConsumeMessageHook)
• Supports topic-based resource naming for fine-grained Sentinel rules
• Auto-configures when both RocketMQ and Sentinel are present
• Exposes configuration via Spring Boot properties

Changes

• Added spring-cloud-alibaba-sentinel-rocketmq module
• Implemented producer and consumer interceptors using Sentinel Entry API
• Added auto-configuration with @ConditionalOnProperty support
• Included unit tests for auto-configuration
• Updated parent pom and dependencies BOM

Configuration Example

spring:
  cloud:
    sentinel:
      rocketmq:
        enabled: true
        producer:
          flow-control-enabled: true
          circuit-breaker-enabled: true
          resource-prefix: "rocketmq-producer:"
        consumer:
          flow-control-enabled: true
          circuit-breaker-enabled: true
          resource-prefix: "rocketmq-consumer:"

Testing

• Unit tests for auto-configuration included
• Tested with RocketMQ 5.3.1 client
• Compatible with Spring Boot 4.x and Java 17+

Fixes #3854
