Description

This is the continuation of HDDS-7935.

In HDDS-7935 we replaced LoadingCache's maximumSize() with softValues(). But there are concerns regarding JVM GC's undeterministic behavior of invalidating the cache entries with the soft references.

In this jira, we are going to implement a custom SnapshotCache to replace LoadingCache gain full control over snapshot cache entry eviction/invalidation.
