> Metastore currently uses black/white list to specify patterns of tables to load into
the cache. Cache is loaded in one shot "prewarm", and updated by a background thread. This
is not a very efficient design. 
> In this feature, we try to enhance the cache for Tables with LRU to improve cache utilization.
