[enhancement] Business Metric Monitoring​

[sadadw1]

Unlike service performance and availability metrics, ​​business metrics​​ are custom-defined indicators that can be preset in monitoring configurations. By integrating with ​​OzHera's alerting functionality​​, they enable ​​business-level monitoring and alerting​​.

For example:

• In an e-commerce system, verifying whether the ​​order amount​​ matches the ​​financial payment amount​​.
• Tracking whether ​​coupon issuance​​ aligns with ​​coupon redemption​​.
