[CARBONDATA-3620][CARBONDATA-3622] Update does not load cache in memory, behavior inconsistent with scenario when index server is not running Problems 1: Segments for prepriming were never being sent to the index server after update success. 2: While dropping a table the table is dropped first and then clear datamap is called, If the table is being accessed somewhere while clearing datamaps in the index server then it will fail and throw exception, thus the cache value will never be cleared. Solutions 1: Segments for prepriming to the index server added after Update success. 2: While dropping the table, to clear cache first and then drop the table. This closes #3511
