    [CARBONDATA-914] Clear BTree and Dictionary instances from LRU cache on table drop

    After drop table dictionary and BTree instances are not getting cleared from driver memory.
Due to this memory will keep growing and after some time GC problems will occur. In real case
scenarios usually driver memory is on lower side hence it is more prone to GC problems.
    
    Solution: When a table is being dropped clear BTree and dictionary instances from LRU
cache.
