Aashish Pant 794ccfde89 Task 6532943: Rocksdb - SetCapacity() can dynamically change cache capacity if feasible 
Summary:
When new capacity is larger than existing capacity, simply update the capacity to the new valie
When new capacity is less than existing capacity, but more than the usage, simply update the capacity to new value
When new capacity is less than the existing capacity and existing usage both, try to purge entries in LRU if feasible to make usage < capacity

Test Plan: Created unit tests in cache_test.cc
