Detailed Description

Simple in-memory cache for UserIdentity objects indexed by user ID, actor ID and user name.

We cannot just use MapCacheLRU for this because of eviction semantics: we need to be able to remove UserIdentity from the cache even if user ID or user name has changed, so we track the most accessed VALUES in the cache, not keys, and evict them alongside with all their indexes.
