Description

In current implementation, affinity storage and affinity calculation are located in cache.
It is not optimal:
1. affinity is not shared between Cache instance with same name
2. affinity mapping requests per cache and add additional loads.
3. if we start implementing transactions or expiry policy, this can be an issue.

I propose to move affinity storage to Client and AioClient.
