Description

需求是这样的：当通过读取配置接口成功获取配置后，Apollo将标识IP为使用最新配置的实例，但实际上获取到配置后还需要做一些额外的工作，比如对配置进行解析、清除缓存等等。这些工作是可能失败的，导致新配置并没有应用到。 所以我想了一个解决方案，就是读取配置接口加上一个参数代表是否手动应答，默认是否，不影响现在的机制。当读取配置接口传入手动应答参数为是时，完成额外工作后，需要再调用一个新的应答接口代表更新配置完成。如果不调用应答接口，则实例仍然是使用非最新配置的实例。 不知道能否支持，谢谢～

Research direction
Investigate the existing configuration retrieval API in Apollo (e.g., ConfigFileController or ConfigService). Understand how the client currently acknowledges config updates. Design a new endpoint for manual acknowledgment and modify the instance status logic. Check the issue comments for any maintainer feedback on the feasibility.
