> This issue is about adding configuration options to add/remove from the block cache when creating/closing files.  For use cases with lots of flushing and compacting, this might be desirable to prevent cache misses and maximize the effective utilization of total block cache capacity.
> The first option, {{hbase.rs.cacheblocksonwrite}}, will make it so we pre-cache blocks as we are writing out new files.
> The second option, {{hbase.rs.evictblocksonclose}}, will make it so we evict blocks when files are closed.
