      Expose two configurable options that control the targeted and maximum levels of dirty data allowed in cache. The options will accept a floating-point value in gigabytes, like cacheSizeGB.

      eviction_dirty_target can be thought of as the targeted amount of dirty data allowed in cache. Anything larger, and worker threads start eviction.
      eviction_dirty_trigger can be thought of as a maximum amount of dirty data allowed in cache before application threads start eviction.
