Description

Currently, we perform affinity re-calculation for each of cache groups, even if configurations (CacheMode, number of backups, affinity function) are equal.

If two cache groups have similar affinity function and number of backups we can calculate affinity prototype for such groups once and re-use in every cache group.

This change will save time on affinity re-calculation if a cluster has a lot of cache groups with similar affinity function.
