Unify and simplify the deduplication caches

      Description

      As a preparation to enable better monitoring and add more precise monitoring probes to the deduplication caches I would like to unify their interfaces and simplify their setup.

      • Don't expose the cache statistics via the FileStore and leverage the the FileStoreBuilder instead for this.
      • All deduplication caches should implement a unified Cache interface to simplify wrapping them (e.g. for additional access statistics collection).
      • Replace the ad-hoc collection of cache statistics in the NodeWriteStats inner class of the SegmentWriter and replace it with a more structured approach.
      • Expose additional cache access statistics via Metrics.
      • The additional statistics should discriminate caches access occurring as regular writes from such occurring during compaction.
