### Description The prometheus metrics we record are stored in LRUs, and although there is no memory leakage, the metrics are not eliminated until they reach the upper limit of the LRUs. As the metrics become more and more numerous, the prometheus server consumes more and more CPU when pulling data, and a mechanism is needed to eliminate the outdated data. Fixes #9627 ### Checklist - [x] I have explained the need for this PR and the problem it solves - [x] I have explained the changes or the new features added to this PR - [x] I have added tests corresponding to this change - [x] I have updated the documentation to reflect this change - [x] I have verified that this change is backward compatible (If not, please discuss on the [APISIX mailing list](https://github.com/apache/apisix/tree/master#community) first) -- This is an automated message from the Apache Git Service.
