[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.
