Move cache measurement logic into separate service #4690
Description
Problem
We currently maintain both CacheService and CacheClient as separate entities with different interfaces, even though they share the same responsibility and effectively perform the same behavior. In practice, CacheService is simply a measurable version of CacheClient, but they are implemented as if they were unrelated components.
This makes unnecessarily too complex.
Solution
Logic related to measurements will be moved into dedicated service.
